Variant files the previous batch missed (run20 compared a different expected variant than run19 did): alter_table/copy2 \d+ Compression column, create_index float formatting, spgist ordering, gpcopy_encoding baked temp-file warnings, select_parallel plan shapes, and qp_misc_jiras now that the Agg-renumber fix lets it run to completion under ORCA.

The expected file asserted 'attribute 3 of relation does not exist' for an UPDATE that moves a row across partitions and segments with RETURNING -- that was the split-update dropped/translated-colnos bug, fixed in 4f73c1c; the statement now returns the moved rows. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
The PG14 'EXPLAIN ... CREATE TABLE AS EXECUTE' test prints actual rows for a Redistribute Motion's receiving slice; how the generated rows split across segments varies with which segment the one-time filter picked, so the counts flap between runs. Mask them with a test-local matchsubs. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
These two tests are .source-generated: pg_regress rewrites expected/*.out from output/*.source at run start, so the earlier regenerations of the .out files were silently overwritten every run. Apply the vetted content to the sources instead (reverse-substituting @abs_builddir@/@abs_srcdir@/@testtablespace@; round-trip verified byte-identical against the run output): - copy: statement triggers are unsupported, so the PG14 COPY progress section reports the create-trigger error and no progress INFO lines - tablespace: REINDEX CONCURRENTLY downgrades with a NOTICE on user tables (system catalogs now refuse like upstream), and the non-concurrent path reports 'only shared relations can be placed in pg_global' for user relations Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Every TupleSplit-based plan for two or more DISTINCT-qualified aggregates produced NULL (sum) / 0 (count) results on both planner and ORCA-fallback paths. ExecBuildAggTrans guards each transition with '<AggExprId column> == aggref->agg_expr_id - 1', but the guarded partial stage's Aggref instances are flat-copies made by make_partial_grouping_target() before fetch_multi_dqas_info() stamps agg_expr_id on the cost-list instances: the partial copies kept 0, every guard compared against -1, and no transition ever advanced. (Single-DQA and colocated single-phase plans were unaffected, which is why simple sanity checks passed.) Propagate the assigned ids into the partial targetlist's Aggrefs by aggno, which stage instances share; also stamp the final-stage instance in the assignment loop for consistency. Verified: grouped and ungrouped multi-DQA over single tables and joins now return correct values on both optimizers (previously NULL/0); single-phase results unchanged. Note: expected files regenerated while this bug was live may have baked NULL aggregates; the next full run flags them as diffs against the now-correct output.

bfv_aggregate, gp_aggregates, gp_dqa and qp_misc_jiras had NULL/0 multi-DQA aggregates baked in by regenerations performed while the TupleSplit guard bug (fixed in 3cab355) was live; refresh them from run23's corrected results. Also port external_table to its .source (the SREH sums over error-logged reads are correct again) and refresh table_functions' optimizer variant.

With default_statistics_target=4 the sampled n_distinct/correlation merged for the partitioned root flap across runs (-0.522/-0.499/ -0.493, 198/196/200). Mask just the root rows of those pg_stats dumps with a test-local matchsubs; the child-partition values stay asserted. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
- uao_dml/uao_ddl templates: AO VACUUM currently leaves the table's index reltuples at 0 (stable across runs; the proper stats update is a separate minor defect), and PG14 initializes reltuples to -1 at creation; align the .source outputs. - incremental_analyze: the root-stat mask needed to tolerate trailing whitespace in result lines. - table_functions: mask the Sort/HashAggregate/Unique trio inside the recorded describe() plan dumps; the choice flips with sampled stats across cluster lifetimes. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
ORCA can place aggregates of different stages into a single Agg node (e.g. a finalize-stage sum(int8) beside a single-stage count over deduplicated input in CTE-sharing DQA plans); the translator sets the node's aggsplit from the first Aggref. The executor's serial/ deserial/final function choices are per-Aggref already, but the transition-vs-combine choice keyed off the node: a combining aggregate then got the plain transition function and accumulated the serialized state datums of the stage below as if they were inputs -- sum() returned sums of raw datum bits (qp_with_clause's nested-CTE query returned 0 rows after its division filter ate the garbage). The finalize step's skipfinal test had the same node-level keying. Use the Aggref's own aggsplit in both places. Verified: the qp_with_clause CTE/DQA query returns exactly the expected region aggregates on ORCA; multi-stage and multi-DQA batteries are unchanged on both optimizers.

- gp_dqa/aggregates optimizer variants: refresh from run25 -- they carried mixed-aggsplit-era artifacts (sum=0; 'aggregate 2108 needs to have compatible input type' error baked as expected). - create_index: the point KNN queries order ties (Infinity vs 1e+300 distances) nondeterministically across runs; add an f1[0] tiebreak and align expected row order. - table_functions_optimizer: gpdiff applies matchsubs embedded in each file, so the variant needs the SORT_OR_HASH directives and normalized plan-op names too.

PG14's preprocess_aggrefs() only walks the targetlist and HAVING qual. A TableValueExpr subquery can SCATTER BY an aggregate expression, and its Aggref copy stayed unnumbered (aggno -1) while the targetlist instance got numbered: the equal() comparisons that match the scatter locus and the Motion hash expressions to the aggregate's output column failed, yielding 'could not find hash distribution key expressions in target list' or a raw 'Aggref found in non-Agg plan node' at execution (table_functions SCATTER BY median/count).

The merge replaced create_one_window_path's GPDB block with upstream's sort-only logic, losing the call to cdb_prepare_path_for_sorted_agg(): nothing enforced that a window's input be gathered (no PARTITION BY) or redistributed by the partitioning keys. Every partitionless window function on the planner path computed per segment -- row_number() OVER (ORDER BY v) returned 1,1,2,1,2,2 -- and a presorted (index KNN) input skipped even the accidental gather, which is what create_index_spgist's seq-vs-index comparisons tripped over. Re-add the helper before the upstream sort logic, recomputing is_sorted afterwards so a merge-gathered input isn't re-sorted. Verified: global row_number over distributed input, partitioned ranks, ORCA parity, and the spgist KNN row_number CTAS probe. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Upstream PG14 removed the deprecated trailing WITH clause from CREATE FUNCTION, but GPDB uses it for its own function attributes -- notably WITH (describe = ...) callbacks for dynamically-typed table functions. After the merge every such CREATE FUNCTION failed with a syntax error and the table_functions suite cascaded into missing-function errors (and the describe() plan-dump sections silently disappeared). Re-add opt_definition to the three CREATE FUNCTION productions, concatenated into options like PG13 did; compute_function_attributes still understands the GPDB items.

The merge kept the WITH (describe = ...) option parsing and the whole
pg_proc_callback machinery, but CreateFunction() no longer called
validate_describe_callback(): describeFuncOid stayed invalid, no
callback row was stored, and every dynamically-typed table function
demanded an explicit column definition list ('a column definition
list is required for functions returning record' across
table_functions). Restore the call after the AS clause is
interpreted, like PG13.
Verified: pg_proc_callback row present; SELECT * over a describe-
typed sessionize() resolves its row type dynamically.

bfv_olap, filter, gp_create_view, olap_window_seq, psql_crosstab, select_parallel and create_index_spgist carried outputs computed under the per-segment window bug (or, for spgist, were regenerated with the broken plan shape during this campaign); refresh from run27's globally-correct results. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
…lyze - table_functions: port the post-describe-restoration output into the optimizer-variant source (dynamic typing works again; the explicit column list on an OUT-parameter describe function now reports 'redundant', matching the function's resolved signature), and purge stale generated _optimizer.out leftovers that sync tars kept resurrecting on top of the source-generated answers. - incremental_analyze: also mask the root partition's merged n_distinct in the wide composite-array pg_stats rows (sampling flaps 5 vs 6).

The bitmap-scan fetch paths of both append-optimized AMs returned tuples without filling the slot's tableOid. The tableoid junk column of a multi-relation UPDATE/DELETE then read 0, which compared equal to the executor's initial mt_lastResultOid and skipped the per-row result-relation lookup: the row was processed against the preloaded first result relation. In qp_dropped_cols, a row that had just moved into an AOCS partition was deleted via heap_delete() on a *heap* sibling partition with the AO pseudo-TID, failing with 'could not open file ... (target block 33554432)' whenever the planner picked a bitmap scan -- and silently corrupting the wrong table in shapes where the block number happened to be readable. Verified on a frozen reproduction database: the scan now reports the correct tableoid and the previously-failing DELETE removes the row from the right partition.

The expected file was baked under an older matchsubs scheme (pg_ao_aux_table_xxxxx); the current init_file masks the names as pg_ao*_OID, same as the already-refreshed AOCS sibling. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
This reverts commit 9aa93e7.
UPDATE/DELETE on an AO auxiliary table (aoseg/aoblkdir/aovisimap -- heap-storage relations with their own relkinds) had no row identity: the planner's add_row_identity_columns() only recognized relation/matview/partitioned, and the executor's relkind grouping put them in the wholerow else-branch, failing with 'could not find junk wholerow column' (uao/uaocs_catalog_tables' maintenance deletes; a regeneration had baked the error into the AOCS expected file, and gpdiff perl warnings made the AO-row sibling false-pass for several runs). Treat the auxiliary relkinds like plain relations on both sides: ctid + gp_segment_id junk in the planner, ctid lookup at executor init. Verified: DELETE FROM pg_aoseg.pg_aoseg_<oid> plans and executes. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
The two expected files had the pre-fix "could not find junk wholerow column" errors baked in (and the downstream poisoned counts: leftover dummy aoblkdir entry, __gp_aovisimap NULL error). With row identity on AO auxiliary relations fixed (553d221), the aux DML succeeds again; regenerate both files from a vetted run30 (636/638, only these two failing, diffs exactly the delete-now-succeeds flip). Also split the init_file pg_ao(cs)?seg_\d+ mask into two capture-free rules. The optional (cs) group left $1 undefined for row-oriented AO names, and interpolating it produced "Use of uninitialized value $1" perl warnings inside gpdiff's eval — which intermittently derailed the comparison and made uao_catalog_tables FALSE-PASS in runs 26-28. Verified standalone: oid-differing files now compare clean with empty stderr, real differences still exit 1. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
The PG14 merge brought pageinspect--1.8--1.9.sql, gistfuncs.c and default_version=1.9 but kept the old Makefile: the 1.9 script was not in DATA (so CREATE EXTENSION failed with "no installation script nor update path for version 1.9") and gistfuncs.o was not in OBJS (so the .so lacked gist_page_opaque_info/gist_page_items[_bytea]). This aborted the entire src/test/isolation suite at setup, which installs the extension before running. Verified: extension creates at 1.9; gist_page_opaque_info and gist_page_items return sane data against a live GiST index. Note the rebuild needs touched sources: the .o files are intermediates, so with sources older than the existing .so make skips the relink. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
…file test Three GPDB test-harness sources still used PG13-era APIs, so the whole isolation2 and heap_checksum suites failed to BUILD during installcheck-world (the suites never ran): - isolation2_main.c: regression_main() grew a postprocess_result_function parameter; pass NULL like src/test/isolation/isolation_main.c. - workfile_mgr_test.c: LogicalTapeSetCreate() grew the bool preallocate parameter (2nd position); pass false. - heap_checksum_helper.c: DropRelFileNodeBuffers() now takes an SMgrRelation instead of RelFileNodeBackend; wrap with smgropen(..., SMGR_MD). All three directories now compile and link (pg_isolation2_regress, isolation2_regress.so, heap_checksum_helper.so). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
…mtuples PG14 changed never-vacuumed/never-analyzed relations to carry reltuples = -1 instead of 0. cdb_estimate_partitioned_numtuples() summed the raw value, so a never-analyzed relation (or -1 per child for partitioned ones) made ORCA's relstats num_rows negative instead of 0, relation_empty came out false, and ORCA derived statistics for such relations — spraying "One or more columns ... do not have statistics" NOTICEs that GPDB 6 never issued. With gp_autostats_mode defaulting to none in ADB, this contaminated the output of nearly every non-regress suite in installcheck-world (fsync, walrep, file_fdw, all of contrib/ indexscan, gpmapreduce, ssl, ...), whose expected files carry no masks for it. Clamp negative reltuples to 0 per the function's documented contract (never-analyzed => 0 rather than a default estimate). Verified live: unanalyzed table and 3-part partitioned table query silently and correctly under optimizer=on; post-ANALYZE behavior unchanged. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
…pe, dumpBaseType, dumpAgg) The PG14 merge combined the GPDB prepared-query versions of several per-object queries with upstream PG14's direct query builders, leaving both halves in four different broken shapes: - dumpFunc/dumpRangeType: the PREPARE executed, but the retained direct builder then appended its full SELECT onto the un-reset buffer, so the first function/range type dumped died with 'syntax error at or near "proretset"'. Replaced the dead builders with the EXECUTE the other prepared sites use, and added the PG14 columns the PREPAREs lacked (pg_get_function_sqlbody AS prosqlbody; rngmultitypid AS rngmultitype). - dumpBaseType: the EXECUTE was correct so the retained builder was dead code, but the PREPARE itself was the PG13-era column set without typsubscript/typsubscriptoid; the reader's atooid(PQgetvalue(-1)) segfaulted on the first base type. Added the gated columns to the PREPARE and removed the dead builder. - dumpAgg: the legacy column list was pasted INSIDE the PREPARE (plus a duplicated aggfinalmodify block), producing one statement with two SELECT lists — the PREPARE itself failed. Removed the duplicate. This broke ANY pg_dump of a database containing user functions, base types, ranges or aggregates, and was the cause of the pg_upgrade check failure in installcheck-world (pg_upgrade dumps with --binary-upgrade). Verified: pg_dump -s and pg_dump -s --binary-upgrade of the regression database both complete cleanly (164k/525k lines, empty stderr). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
The merge dropped one GPDB line from errstart(): setting
omit_location = false alongside the default ERRCODE_INTERNAL_ERROR for
elevel >= ERROR. Without it cdb_tidy_message() never appended the
" (file.c:NN)" suffix, so every elog(ERROR)/ereport-without-errcode
message lost its location — visible as extprotocol's expected
"This is greenplum. (gpextprotocol.c:56)" coming back bare, and many
isolation2 expecteds carry such suffixes too.
Blast radius checked: errcode()-carrying classes (e.g. fault injector's
XX009) were never suffixed by this path, so the campaign-era expected
files baking bare fault messages stay correct; the "could not devise a
plan" class is masked by init_file either way; errors-at-eox (suffixed
fault expectations) is not in any schedule.
Verified live: SELECT array_in('{1}', 0, -1) again reports
"cache lookup failed for type 0 (lsyscache.c:NNNN)".

PG14 renamed configure's output variable: Makefile.global now exports
only with_ssl (= openssl), while nine GPDB makefile gates still tested
the removed with_openssl. Every such conditional silently went false:
- contrib/sslinfo was never built or installed ("could not open
extension control file ... sslinfo.control" — failed both ssl suite
tests in installcheck-world)
- src/common built the FALLBACK cryptohash/hmac/sha2 instead of the
OpenSSL EVP implementations
- src/test/ssl, src/test/modules (ssl_passphrase_callback), gpfdist
ssl regress bits, and gpdemo's ssl demo path were all skipped
Switch all gates to upstream's ifeq ($(with_ssl),openssl) form, export
with_ssl for gpdemo, and drop sha2_openssl.o from the OpenSSL branch
(PG14 folded SHA-2 into the EVP cryptohash; the file no longer exists).
Also add HMAC_CTX_new/HMAC_CTX_free to the generated configure's
OpenSSL function checks: configure.ac has them but configure was never
regenerated, and without HAVE_HMAC_CTX_NEW hmac_openssl.c does
sizeof(HMAC_CTX), which is an incomplete type on OpenSSL 1.1+.
Verified: sslinfo installs and ssl_is_used() works; md5()/sha256()
match reference digests with the EVP implementations linked in
(nm: EVP_DigestInit imported by postgres).

The GppcReportLevel enum values are a published partner ABI equal to the elog levels of pre-14 servers (GPPC_ERROR = 20). PG14 inserted WARNING_CLIENT_ONLY at 20 and moved ERROR to 21, and GppcReport() passed the value through numerically — so GppcReport(GPPC_ERROR) emitted a client-only WARNING and execution continued past what should have been an aborting error (all three gppc test files failed with ERROR->WARNING demotions cascading into 4400 diff lines). Map levels explicitly in both directions: GppcReport() converts GPPC levels to server levels, GppcGetReportLevel() converts the server elevel back (WARNING_CLIENT_ONLY reports as GPPC_WARNING, ERROR and above as GPPC_ERROR). The public enum stays untouched for ABI compatibility. Verified: gppc_basic and gppc_demo pass; tabfunc_gppc_demo is down to 38 diff lines of unrelated upstream output drift (pg_type.typsubscript row, EXTRACT column header) to be regenerated.

…ipe hang) PG15 (upstream b073c3c) revoked the default CREATE privilege on schema public from PUBLIC. orafce's dbms_pipe session tests create helper functions in schema public under a non-superuser role (pipe_test_owner). Under PG15 those CREATE FUNCTION statements now fail with "permission denied for schema public", so session A never sends its pipe messages and session B blocks forever in dbms_pipe.receive_message() -- the whole orafce installcheck hangs at the dbms_pipe_session_A/B parallel group. Restore the test precondition by granting CREATE on public in init.sql, which runs (and commits) before the parallel A/B group. This mirrors the same adaptation already applied to the core regress (test_setup.sql) and isolation2 (setup.sql) suites for this PG15 change. The statement runs in the existing \set ECHO none / client_min_messages=error region, so it adds no output and needs no answer-file change. With the grant, all 13 orafce tests pass (verified on a freshly restarted cluster, since dbms_pipe pipes live in coordinator shared memory and survive DROP DATABASE). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
The PG15 merge (67c0b3d) misplaced the GGDB-specific gp_file_fdw test templates into sql/ and expected/, but pg_regress's convert_sourcefiles() only processes input/*.source -> sql/*.sql and output/*.source -> expected/*.out. With the templates in the wrong directories the .sql/.out were never generated, so the test ran an empty file and failed with "cat: .../sql/gp_file_fdw.sql: No such file or directory". The templates use @abs_srcdir@ / <SEGID> tokens that *require* the substitution convert_sourcefiles performs, and on the PG14 baseline (claude-merge-2) they correctly lived in input/ and output/. Move them back. With this, gp_file_fdw passes under both optimizer=on and optimizer=off. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
The PG15 merge took upstream's contrib/file_fdw/expected/file_fdw.out
wholesale, dropping the GGDB-specific EXPLAIN output the PG14 baseline already
had:
- the "Optimizer: Postgres query optimizer" footer (ORCA falls back to the
Postgres planner for foreign scans) -- present 4x in the PG14 expected;
- "Result / One-Time Filter: false" instead of "Foreign Scan / Filter
(a < 0)" for the constraint-exclusion test, because GGDB defaults
constraint_exclusion = ON (guc.c) vs upstream's "partition", so the
CHECK (a >= 0) on agg_csv proves a < 0 always false.
Both are long-standing GGDB behavior (verified against claude-merge-2), not PG15
changes. Safety gate: the only diffs are EXPLAIN output; every query result row
is unchanged (e.g. SELECT * FROM agg_csv WHERE a < 0 still returns 0 rows). The
base file_fdw.out is shared by both optimizers and verified green under
optimizer=on and optimizer=off (foreign scans always fall back to the planner).

…List crash)
SetupTCPInterconnect() trims registered connections from the incompleteConns
list as it processes them. It used the pre-PG13 linked-list idiom of fetching
the next cell *before* deleting the current one:
cell = list_head(incompleteConns);
while (n > 0 && cell != NULL) {
conn = lfirst(cell);
cell = lnext(incompleteConns, cell); /* advance first */
...
incompleteConns = list_delete_ptr(incompleteConns, conn); /* then delete */
}
PostgreSQL's List is now an array (PG13 1cff1b9). list_delete_ptr() shifts
the underlying element array (and may realloc it), so the already-advanced cell
pointer is left dangling/out of bounds; the next lnext() trips
Assert(c >= &l->elements[0] && c < &l->elements[l->length]) (pg_list.h)
and the backend aborts during ExecutorStart -> SetupInterconnect ->
SetupTCPInterconnect. This crashes any query using the TCP interconnect
(gp_interconnect_type=tcp, and proxy which reuses the TCP setup) whenever a
connection is removed during the registration loop; the isolation2
tcp_ic_teardown test hit it deterministically and crashed the coordinator.
Switch to the array-List-safe idiom foreach() + foreach_delete_current(), which
deletes the current cell and adjusts the loop position correctly -- the same
pattern already used elsewhere in this file (TeardownTCPInterconnect).
ic-tcp isolation2 schedule now passes.

…d behavior
Two behave scenarios failed on the PG15 CI even though the backend behaves
correctly; the step assertions were fragile against how the behavior surfaces.
Verified both backend mechanisms locally (psql / direct reproduction) and made
the steps robust without weakening what they verify.
1. gpexpand "transaction which wants to change the catalog must be aborted"
(verify that long-run transaction aborted ...). After an online expand, a
stale transaction's catalog change is correctly rejected by
gp_expand_protect_catalog_changes() with
ereport(FATAL, "cluster is expanded from version N to M ...").
FATAL is intentional and required (an ERROR-and-continue session would keep
its stale gang and run queries on the old segment set -> wrong results,
notably for temp-namespace sessions that cdbcomponent never refreshes).
Because FATAL tears down the connection, the detail message is delivered to
some libpq versions but not others -- psycopg2 (libpq 14.2) surfaces only
"server closed the connection unexpectedly". The transaction is aborted
either way, so accept that form in addition to the explicit message.
2. gprecoverseg "should not give warning if pg_basebackup is running"
(gp_stat_replication table has pg_basebackup entry for content N). The
running pg_basebackup's entry is correctly present, but this check runs right
after an FTS probe is reconfiguring other contents, and the
gp_stat_replication gather can momentarily miss it during that flux. Poll for
up to 30s instead of querying once.
Reproduced the exact mechanisms in a single-node cluster and confirmed both
steps pass with these changes (the gpexpand FATAL is raised and recognized; the
pg_basebackup entry is found, even with the wal_sender_loop suspend fault the
scenario uses).

…rror paths
Three except blocks reported segment-info query failures with
raise Exception("... %s" % e.message)
but Python 3 exceptions have no .message attribute, so on the failure path this
raises AttributeError and masks the real error (the same class of failure-
masking seen elsewhere in the behave harness). Use str(e).
Found while sweeping mgmt_utils.py for assertions that depend on a backend
error message surviving to the client. The only FATAL-message assertion (the
gpexpand "cluster is expanded from" check) was already made robust; no other
step file relies on a FATAL message reaching the psycopg2 client.

Adds src/test/regress/sql/pg_dump_gp_roundtrip.sql (greenplum_schedule, after pg_dump_binary_upgrade) covering pg_dump + restore of the full Greenplum storage/distribution matrix and asserting nothing is lost in the round trip: * distribution policy + key: hash, multi-column hash, random, replicated * table access method: heap, append-only row, append-only column * storage reloptions: AOCO with compresstype=zstd / compresslevel * range-partitioned table (root + child partitions) * all row data (per-table counts) The test is self-checking: it captures a structural signature (policytype, distkey, numsegments, access method, sorted reloptions) and per-table row counts before the round trip, dumps the schema, drops it, restores it from the plain-SQL dump, captures the signature again, and asserts both EXCEPT diffs are empty (so the restored schema -- including the partition children -- is identical to the original). A relation-count and row-count guard prevents a false "empty diff" pass if a restore silently produced nothing. This locks down the ~118 pg_dump merge hunks the PG15 merge resolved (distribution clauses, AO/AOCO options, partition DDL). Verified: passes under optimizer=off and optimizer=on (the checks are catalog queries, so no _optimizer.out is needed), and a negative test (sabotaging the dump to drop AOCO compression and flip a random table to hash) makes the diff non-empty as expected.

…drift
Regenerated from the 4-job CI result tarballs (gpdiff success->error gate clean
for each; data rows unchanged):
* copy.out -- reflects the COPY ... HEADER MATCH
validation enforced by 3865973 (header now validated: "column name
mismatch in header line" / "wrong number of fields in header line"
instead of the old header-as-data type errors). Base file (no
_optimizer variant) -> covers all 4 jobs.
* incremental_analyze.out + incremental_analyze_optimizer.out
* vacuum_gp.out -- partitioned-root reltuples now populated
by 664fafd (root stat 0 -> non-zero from merged leaf stats).
* bfv_index_optimizer.out -- ORCA cost-model plan drift (Nested Loop +
Dynamic Bitmap Index Scan); count unchanged. ORCA-only; planner
bfv_index.out untouched.
* dpe.out -- planner agg-strategy drift
(GroupAggregate -> HashAggregate); large git diff is inherent MPP
unordered-row reorder noise (gpdiff sorts at compare).
NOT regenerated (held): dpe_optimizer.out -- under ORCA the plan drops the
Partition Selector (Dynamic Partition Elimination), scanning 6/6 partitions via
a Nested Loop + Dynamic Index Scan instead of pruning to 2. Correctness holds,
but regenerating would defeat this DPE-coverage test; needs an ORCA cost-model
look first.

… (mirror_replay) create_file_for_extract() opened the target with fopen(filename, "wb") without removing a pre-existing file first, unlike its siblings extract_directory() and extract_link() which honor forceoverwrite. During gprecoverseg -aF full recovery, the target may already exist and be read-only (e.g. an append-only segfile chmod'd to 0400, as mirror_replay does to force a truncate-replay PANIC), so fopen(..., "wb") fails with EACCES, the base backup aborts with "could not create file ...", and the mirror is left down (n/d) instead of recovered (s/u). The PG15 bbsink/bbstreamer rewrite dropped GPDB's PG14 force-overwrite remove()-before-create for the regular-file path; the earlier fix db73cce re-grafted the directory and symlink paths but missed this one. Add a forceoverwrite parameter and unlink() the target first when set, mirroring extract_link(), and pass mystreamer->forceoverwrite at the call site. Verified: src/test/regress mirror_replay passes (content-0 mirror is fully recovered to s/u; previously gprecoverseg -aF aborted on the read-only segfile).

…or changes
Three regress failures in the CI matrix were test-harness fragilities exposed by
PG15 behavior changes, not product bugs:
- qp_misc_jiras: the `set statement_mem='1000kB'` set for the count-distinct DQA
test leaked into the incidental \d/\d+ describes further down; under PG15 the
heavier describe catalog query trips the auto-policy per-operator memory floor
("insufficient memory reserved for statement"). Reset statement_mem before the
describe blocks and restore the low setting before the later mem-sensitive
count-distinct EXPLAINs (tbl5994), whose hashagg plans depend on it.
- autostats: add a matchignore for the racy "LOG: An exception was encountered
during the execution of statement:" line (emitted under client_min_messages=log,
ordered nondeterministically against the surrounding output).
- pg_stat: move the settle pg_sleep(10) to AFTER the indexed query rather than
before it. PG15 throttles shared-memory stats updates (PGSTAT_MIN_INTERVAL)
instead of PG14's prompt per-message send, so the index-scan counters need time
to flush before being read or idx_scan reads back as 0.
Answer files regenerated and verified under both optimizers (planner + ORCA) in
fresh databases; gpdiff success->error gate clean (the QE-slice-restriction
errors in qp_misc_jiras are pre-existing and atmsort-normalized).

Resolve all 528 merge conflicts and bring the PG16-based tree up to a working MPP cluster (build-verified; regression hardening to follow). Highlights of the conflict resolution + PG16 API migration: - Node layer: adopt PG16 automated gen_node_support; re-graft GGDB node tags/fields (Plan/Scan/Join abstract-with-tag, is_plan_node rewrite, OidAssignment/CdbExplain_StatHdr), manual copy/out/read serializers. - SHM_QUEUE/PROC_QUEUE -> dlist/dclist (resqueue, resgroup, proc, lock). - RelFileNode -> RelFileLocator across AO/AOCO, bitmap and xlog, keeping GGDB's RelFileNode where the AO WAL format requires it (convert at the boundaries). - Revert the PG15-beta SQL/JSON query nodes; outer-join refactor (nullable_relids/outerjoin_delayed -> incompatible_relids/has_clone); RangeTblEntry perms -> RTEPermissionInfo; pg_upgrade DbInfo locale; orafce/pg_rewind/pg_dump and a large tail of signature changes. - initdb: satisfy PG16 check_GUC_init (GUC boot_val/C-var consistency, NO_SHOW_ALL flag rule) and fix guc_malloc check hooks, bootstrap backend-type, and the MPP pg_stat_* views. - Cluster bring-up: recovery_prefetch default off, RTE_VOID perminfo, OidAssignment copyObject, PlannedStmt.permInfos dispatch, zero-perm ExecCheckPermissions skip, and VACOPT_PROCESS_MAIN in AO vacuum dispatch. Verified: full build+link, mock unittest-check, initdb, gpdemo cluster (mirrors+standby), and distributed INSERT/SELECT/JOIN/UPDATE/DELETE + VACUUM. Regression matrix triage is the next step.

Follow-up fixes on top of the PG16 merge, found during the regression matrix bring-up: - cdbpath.c: handle JOIN_RIGHT_ANTI (new in PG16) in the join-locus switch (mirror JOIN_RIGHT: the inner/right side is preserved, so it cannot be replicated). - outfuncs.c: restore GGDB's RTE_TABLEFUNCTION and RTE_VOID cases in _outRangeTblEntry (the merge dropped them; RTE_VOID nodeToString hit "unrecognized RTE kind: 9"). - cdbplan.c: teach plan_tree_mutator about T_Memoize and T_IncrementalSort (mirror T_Material / T_Sort). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
GreengageDB's MPP plan walkers/mutators/executor-squelch do not handle the Memoize and IncrementalSort plan nodes (they hit "unrecognized node type" in plan_tree_walker -> expression_tree_walker, and in ExecSquelch), so these upstream planner features are not supported under MPP. Turn them off by default (both the C-variable and the GUC boot_val), matching the prior PG15 behavior, which clears the whole crash class (type_sanity, opr_sanity, and many cascading failures). Also teach plan_tree_walker about T_Memoize / T_IncrementalSort (as with plan_tree_mutator) so the walker stays correct even if the nodes appear.

…t=off) Brings parallel_schedule (optimizer=off) from a full crash-cascade to a clean run of 68/203 fails with zero crashes. Fixes the following classes found via cores/gdb + QD/QE dispatch analysis (session 7 + 8): Crash / assert classes: - VACOPT bit collision: PG16's VACOPT_ONLY_DATABASE_STATS(0x400)/SKIP_PRIVS (0x800) collided with GGDB VACOPT_ROOTONLY/FULLSCAN(1<<10,1<<11), so VACUUM (ONLY_DATABASE_STATS) spuriously set ROOTONLY and tripped the assert in vacuum(). Shift GGDB flags to bits 12-16 (vacuum.h). - _copyMotion senderSliceInfo memcpy-from-NULL: gen_node_support.pl now NULL-guards the GPDB PlanSlice* copy. - T_PathTarget / T_OidAssignment copyObject (copyfuncs.c manual section). - default_transaction_isolation lost check_DefaultXactIsoLevel hook in the merge -> serializable snapshot assert; rewire hook (guc_tables.c, guc_hooks.h). - snapmgr.c subxip pg_lfind32 XactIsoLevel guard (both call sites). - analyze.c hll: read typlen/typbyval/typalign from attrtype not the fake attr (extended-stats SIGSEGV). - planner.c: drop stale parse==root->parse assert (PG16 remove_nulling_relids reassigns root->parse). - bitmapattutil.c: PG16 split _bt_getbuf; LOV index new-page via _bt_allocbuf(lovIndex, lovHeap). QD/QE dispatch desyncs: - AlterTableCmd.recurse (PG16-new field) missing from _out/_readAlterTableCmd -> QE saw recurse=false -> "column must be added to child tables too" on segments + INSERT/column cascades (outfast.c, readfast.c). - RangeTblEntry RTE_SUBQUERY view fields + RTE_TABLEFUNCTION/RTE_VOID kinds missing from hand serializers (outfast.c, readfast.c, readfuncs.c). - pg_auth_members OID: GetNewOidForAuthMember + GrantRole assigns/dispatches OIDs (oid_dispatch.c/.h, user.c). Planner (MPP grouping): - processed_groupClause/processed_distinctClause replace parse->*Clause across the cdb grouping/distinct paths so labels match make_group_input_target (planner.c, cdbgroupingpaths.c). Soft-error input contract (PG16 pg_input_is_valid): - float8in_internal honors escontext in the GGDB strtold overflow recheck (float.c). - complex_in/complex_decode_double thread escontext + SOFT_ERROR_OCCURRED (complex_type.c).

…ed-agg (opt=off) Three real bug classes found via parallel_schedule opt=off triage: 1. RTE_VOID dispatch drops relid/relkind (perminfo-mismatch crash on QE). _out/_readRangeTblEntry serialized perminfoindex unconditionally but wrote nothing for RTE_VOID, so a pulled-up view RTE (marked RTE_VOID, relid kept on the QD) arrived at the QE with relid=0 while its RTEPermissionInfo kept the real relid -> ExecCheckPermissions sanity check "permission info at index N ... does not match provided RTE" (parse_relation.c:4222) on the segment. Serialize relid/relkind/ rellockmode for RTE_VOID like RTE_SUBQUERY. Fixes updatable-view-on- INSTEAD-rule UPDATE/returning/subselect. 2. VACUUM (SKIP_DATABASE_STATS|ONLY_DATABASE_STATS) "unrecognized vacuum option 200". PG16's new VACOPT bits were not emitted by the QD's optmask->DefElem converter (vacuum_params_to_options_list); ExecVacuum already parses them back. Also clear the internal SKIP_PRIVS bit so it never trips the leftover-option check (each node re-derives it). 3. count(x), count(DISTINCT x) where x is the distribution key -> "could not find pathkey item to sort (createplan.c:7468)". PG16's new enable_presorted_aggregate adds a pathkey on the DISTINCT argument to group_pathkeys; the MPP multi-stage grouping planner does not carry that column through every intermediate tlist. Disable it by default, as with enable_memoize / enable_incremental_sort, until MPP supports it. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
AlterRole() (which handles ALTER GROUP grp ADD/DROP USER) dispatched the statement with NIL oidAssignments. In PG16 pg_auth_members has an OID column, so AddRoleMems now assigns a pg_auth_members OID on the QD via GetNewOidForAuthMember; without dispatching it the segment failed with "no pre-assigned OID for pg_auth_members tuple" (oid_dispatch.c:449). Pass GetAssignedOidsForDispatch(), matching the GrantRole() path. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
…lause)
PG16 added column-level STORAGE in CREATE TABLE (e.g. "c text STORAGE
plain"). The parser records it in ColumnDef.storage_name (a string), which
DefineRelation resolves to attstorage (tablecmds.c:1101). The MPP dispatch
serializers _out/_readColumnDef wrote only the legacy char field `storage`,
not `storage_name`, so segments received storage_name=NULL and left the
column at its type default (e.g. text -> extended) while the QD honored the
clause. The divergence surfaced later as a QD/QE desync: a subsequent table
rewrite decided needs_toast_table() differently on the segment, which then
tried to create a TOAST table with no dispatched OID ("no pre-assigned OID
for pg_class tuple pg_toast_N", oid_dispatch.c:449). Serialize storage_name
alongside storage. Fixes the alter_table STORAGE/TOAST section.

…c relocation The PG16 merge relocated the GUC boot-value table from guc.c to guc_tables.c and took upstream's boot_vals, silently reverting GGDB's deliberate planner overrides (zero conflict markers). Most consequentially enable_mergejoin flipped on, so the planner chose a Merge Join for a recursive-union recursive term whose inner is a Broadcast Motion; GGDB's executor re-drives that motion across recursive iterations -> interconnect deadlock (gp_recursive_cte hang ~13min, blocking greenplum_schedule). This is a pre-existing GGDB executor limitation (cm3 also hangs if forced to merge-join it); cm3 only avoided it because enable_mergejoin=off. Restore boot_vals to match cm3 (PG15-green): - enable_nestloop, enable_mergejoin, geqo, jit, hot_standby -> off - logging_collector -> on - from_collapse_limit, join_collapse_limit -> 20 - constraint_exclusion -> on Also update jit_enabled and constraint_exclusion C-var static inits so PG16's check_GUC_init (cassert) does not abort the postmaster. Verified: recursive-CTE query 26ms (was a hang), recursive term now plans as Hash Join, cluster recreated healthy (hot_standby=off does not break mirrors). join_hash's 'illegal rescan of motion' error is also resolved by enable_nestloop=off.

…elocation Follow-up to the planner-GUC re-graft (ef55a52): the same guc.c->guc_tables.c relocation reverted GGDB's non-planner boot_vals to upstream. Restore to match cm3 (PG15-green): - max_connections 100->200 (min 10) - max_prepared_transactions 0->50 (min 1; distributed txns use 2PC) - superuser_reserved_connections 3->10 (min RESERVED_FTS_CONNECTIONS; FTS) - work_mem 4096->32768 - max_locks_per_transaction 64->128 - wal_sender_timeout 60s->300s - wal_keep_size 0->DEFAULT_MIN_WAL_SEGS*seg (320MB; retain WAL for mirrors) - log_filename postgresql-*.log -> gpdb-*.csv - log_rotation_size 10MB->1GB Also update the MaxConnections/work_mem/wal_sender_timeout/Log_RotationSize C-var static inits so PG16's check_GUC_init (cassert) does not abort the postmaster. Verified: cluster recreates healthy (initdb + postmaster pass check_GUC_init), values correct at runtime, distributed DML + 2PC work.

…ACUUM crash)
PG16 added IndexVacuumInfo.heaprel (the heap the index belongs to); btree
vacuum uses it for page recycling (BTPageIsRecyclable needs the heap's xmin
horizon via GlobalVisCheckRemovableXid). GGDB's append-only index vacuum built
IndexVacuumInfo with `= {0}` and never set heaprel, so during an AO/AOCS VACUUM
that compacts a segfile and updates a btree index, btvacuumpage hit
Assert(heaprel != NULL) (nbtree.h:296) -> SIGABRT on the segment -> crash
cascade. The AO table is the "heap" its indexes belong to, so set
ivinfo.heaprel = aoRelation, mirroring lazy_vacuum_index (ivinfo.heaprel =
vacrel->rel) and analyze.c (= onerel). Fixed both sites:
vacuum_appendonly_index (index_bulk_delete path) and scan_index
(index_vacuum_cleanup path).
Fixes the whole AO/AOCS compaction cluster in greenplum_schedule (19 tests):
uao_compaction/* , uaocs_compaction/*, uao_dml/uao_dml_{row,column},
vacuum_full_ao, vacuum_full_freeze_heap, freeze_aux_tables. All verified green.

… build
The PG16 merge was built --disable-orca, so the ORCA translator (src/backend/
gpopt) had never been compiled against the PG16-merged nodes. Enabling ORCA
surfaces two PG16 changes:
1. RTEPermissionInfo refactor: PG16 moved the per-RTE permission-check fields
(requiredPerms, checkAsUser, selectedCols) out of RangeTblEntry into a
separate RTEPermissionInfo list (PlannedStmt->permInfos), linked by
rte->perminfoindex. Ported the translator:
- CContextDXLToPlStmt accumulates a parallel m_rte_perminfos_list;
Add/GetRTEPermissionInfo wrap addRTEPermissionInfo/getRTEPermissionInfo.
- DXL->PlStmt: TranslateDXLTblDescrToRangeTblEntry creates the perminfo and
sets checkAsUser/requiredPerms on it; the scan/index/dyn/DML/bitmap callers
set ACL bits via GetRTEPermissionInfo(rte); PlannedStmt->permInfos wired up;
RTE_VALUES/RTE_SUBQUERY wrappers get no perminfo.
- Query->DXL: GetTableDescr / CheckRTEPermissions thread the query's
rteperminfos to read checkAsUser and call ExecCheckPermissions.
- orca.c: drop requiredPerms on the RTE_SUBQUERY wrapper.
- gpdbwrappers: ExecCheckRTPerms -> ExecCheckPermissions(+perminfos).
2. gporca.mk: PG16 configure adds -Wshadow=compatible-local; the vendored ORCA
C++ has many pre-existing harmless shadows -> filter that flag out of the
gporca CXXFLAGS/BITCODE_CXXFLAGS (subtree only, both .o and .bc compiles).
ORCA now builds, links, and runs on PG16: EXPLAIN reports 'Pivotal Optimizer
(GPORCA)' and SELECT/JOIN/UPDATE/DELETE execute correctly (RTEPermissionInfo
round-trip verified). The gporca regress test now runs; its plan/result drift
is separate opt=on triage.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Both surfaced only under optimizer=on (ORCA) after the PG16 merge; the planner path never exercises this code. 1. transformGroupedWindows (orca.c) — window-over-aggregate crash cascade. ORCA's optimize_query preprocessing splits a query that has BOTH window functions and aggregates into an outer window query Q' wrapping an aggregating subquery Q''. It moved the base-table RTEs into Q'' but left the base table's RTEPermissionInfos on Q' (which now holds only the synthetic "Window" subquery-wrapper RTE, perminfoindex=0). In PG16 rteperminfos is per-Query and must travel with its RTEs, so the orphaned perminfo tripped the ExecCheckPermissions bijection assert (execMain.c:1419) that GGDB runs up-front during query->DXL translation. A single such query (e.g. SUM(SUM(c)) OVER (...) ... GROUP BY) SIGABRT'd the coordinator and cascaded across the whole parallel group. Fix: move rteperminfos into Q'' alongside the rtable and clear it on Q'. 2. TranslateDXLTvf (CTranslatorDXLToPlStmt.cpp) — function-scan coldeflist EXPLAIN VERBOSE deparse. ORCA populated the column-definition metadata (funccolnames/types/typmods/collations, funccolcount) only on the plan node's RangeTblFunction, not on the RTE's. ruleutils/expandRTE resolve a function scan's output column names through the RTE and truncate rte->eref->colnames to funccolcount (0), so EXPLAIN VERBOSE of a record-returning function with a column definition list raised "invalid attnum" (ruleutils.c:7508). Execution was unaffected (it uses the plan node's RangeTblFunction). Fix: mirror the planner by populating the RTE's RangeTblFunction with the same column metadata. Verified live on the gpdb_pg16 ORCA cluster: the window-over-aggregate queries return correct results with no crash, EXPLAIN VERBOSE of a coldeflist function scan deparses correctly, and the opt=on parallel_schedule crash cascade is eliminated (95 -> 81 failing, 0 crashes; remaining failures are stale _optimizer.out answer-file drift). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
After the PG16 merge the ORCA (optimizer=on) answer files had systematically
drifted (they predate the PG16 test reorg), so the opt=on parallel_schedule
reported 81/203 failing purely on cosmetic drift: MPP plan-shape / slice
numbers, ORCA-vs-planner plan differences, new upstream test queries, and
PG16 behavior/error-text changes (datetime, numeric literals, GRANT/RLS
messages, generated-column inheritance, new EXPLAIN/VACUUM options) that were
already reflected in the base .out but not the _optimizer.out.
Regenerated 42 existing + 34 new _optimizer.out from a clean opt=on run
(0 crashes, no memory pressure), safety-gated per the answer-file-regen
protocol:
- per-test success->error scan on the gpdiff regression.diffs (added minus
removed ERROR lines, seg/pid/number-stripped): every net-new error is
confirmed-correct PG16/GGDB behavior, not a hidden regression;
- clean re-run reports ok for all 76 (81 -> 5 failing);
- wrong-data guard: for opt=on-only tests (opt=off green, so base .out is a
trustworthy planner reference) the new _optimizer.out differs from base
.out only in row-order and plan shape, never in data values.
Only touches _optimizer.out, so the planner (optimizer=off) matrix and the
JIT/non-JIT base-.out jobs are unaffected.
Deliberately NOT regenerated (left red):
- constraints - the deferred FK-on-ATTACH-partition pg_constraint OID
dispatch bug (fails both matrices); regenning would mask it;
- select_parallel - flaky EXPLAIN ANALYZE per-segment actual-rows flutter;
- aggregates / jsonb / alter_table - non-deterministic output (a fluttering
aggregate column; \x expanded-record order that atmsort doesn't sort;
runtime relfilenode OIDs baked in a "File exists" error): need an ORDER BY
/ init_file mask / investigation, not a regen.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Follow-up to the _optimizer.out mass regen, resolving three of the five tests that regen alone could not: - select_parallel: clean regen. The drift was the PG16 rename force_parallel_mode -> debug_parallel_query plus new upstream SRF-pathkey tests; deterministic, so the regenerated _optimizer.out is stable. - jsonb: the "\x"-expanded `table test_jsonb_subscript` output returned its two rows in non-deterministic MPP segment order (atmsort does not sort multi-line expanded records). Add ORDER BY id to make it deterministic, then regen. (Changes sql/jsonb.sql, so the base .out will pick this up in the optimizer=off pass; it already fails there on stale drift.) - alter_table: the expected "could not create file base/<db>/<relfilenode>: File exists" error (GPDB does not support ALTER COLUMN SET DATA TYPE on an indexed column, since fecd245) carries runtime-varying OIDs. Add an init_file matchsub normalizing base/N/N -> base/OID/OID (applies to both matrices, masks only the OID, not the error), then regen the new STORAGE tests. Verified: opt=on parallel_schedule now 201/203, stable across re-runs. Remaining 2 (deferred, documented): - aggregates: v_pagg_test's multi-unnest over array_agg/string_agg without ORDER BY flutters run-to-run under MPP; falls back to the planner (not ORCA-specific) and affects both matrices - needs a closer look. - constraints: the FK-on-ATTACH-partition pg_constraint OID-dispatch bug (a real defect, fails both matrices). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
v_pagg_test unnests the results of string_agg/array_agg computed without an
ORDER BY, then takes min/max/count(distinct) over the unnested values. Under
MPP the aggregates collect their elements in non-deterministic segment order,
so the multi-unnest pairing (and hence the downstream results) fluttered
run-to-run. The query falls back to the planner (GPORCA cannot plan multiple
DISTINCT-qualified aggregates), so this was never ORCA-specific.
Add ORDER BY x to the four string_agg/array_agg calls, making element order
deterministic, then regen aggregates_optimizer.out. Verified stable across a
regen-from-run-A / verify-on-run-B cycle.
opt=on parallel_schedule is now 202/203. The one remaining failure,
constraints, is the FK-on-ATTACH-partition pg_constraint OID-dispatch bug: in
ATExecAttachPartition the FK OID is assigned by CloneForeignKeyConstraints
(after AttachPartitionEnsureIndexes/DefineIndex) but does not reach the QE
("no pre-assigned OID for pg_constraint ..._fkey"). It fails both matrices
(not ORCA-specific) and needs runtime tracing of GetAssignedOidsForDispatch to
find which dispatch consumes the list first; deferred.

First opt=on pass over greenplum_schedule (the GPDB-specific suite). The full parallel+greenplum run under ORCA completed without a hang (the session-10c qp_with_clause motion deadlock and the autovacuum fault-hang do not wedge under ORCA - it plans those queries differently), and the marquee `gporca` test passes (its 11K-line drift from the previous session is gone, fixed by the restored GGDB GUC defaults + the ORCA translator port). Of 57 failures, most are the same cosmetic MPP plan-shape / PG16 error-message drift already catalogued for optimizer=off. Regenerated 37 _optimizer.out from the run, safety-gated: per-test success->error scan, then a full re-run - the 37 stay green (57 -> 23 remaining), and the re-run gate caught 7 regens as non-deterministic (reverted: alter_db_set_tablespace, gp_connections, namespace_gp, qp_with_functional_inlining/noinlining, table_functions, truncate_gp - they need ORDER BY / masks / a closer look). Not regenerated (excluded up front): fault-injection tests (which crash by design: replication_slots, subtrx_overflow, gp_tablespace_with_faults, gpcopy), crash-cascade victims from those, the non-deterministic stats tests (pg_stat, pgstat_qd_tabstat, autostats, gp_hyperloglog), and the two real bugs (constraints FK-OID, qp_with_clause). The remaining ~23 are: fault tests + stats (framework-dependent), the 7 non-deterministic stragglers, run-to-run flakes (gp_toolkit, partition_prune, bitmap_index, dboptions), and the 2 real bugs. Only _optimizer.out touched, so the optimizer=off and base-.out jobs are unaffected. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
…nts)
ALTER TABLE ... ATTACH PARTITION of a partition whose parent has a foreign key
clones that FK onto the partition, assigning a new pg_constraint OID on the
coordinator. The QE never received it:
ERROR: no pre-assigned OID for pg_constraint tuple
"parted_fk_naming_1_id_abc_fkey" (oid_dispatch.c:449)
Root cause (traced by instrumenting GetNewOidForConstraint /
GetAssignedOidsForDispatch): after phase 2 assigns the cloned FK's OID, phase 3
runs validateForeignKeyConstraint() -> RI_Initial_Check(), which dispatches a
LEFT JOIN probe query. Its executor start (standard_ExecutorStart ->
GetAssignedOidsForDispatch) grabs and *resets* the pending OID-assignment list,
so the FK OID travels with the throwaway probe instead of the ATTACH statement,
and the ATTACH dispatch reaches the segments with an empty list.
Greenplum does not enforce foreign keys (it already warns "will not be
enforced"), so the initial RI_Initial_Check() validation is pointless here --
and actively harmful: besides stealing the OID on the coordinator, on a QE the
probe query raises "function cannot execute on a QE slice" when a dispatched
ALTER TABLE re-runs phase-3 FK validation. Fix: skip the validation entirely
in validateForeignKeyConstraint() (warn on the coordinator, then return). No
probe query -> no OID theft, no QE-slice error. The FK catalog entry is still
created and dispatched, so the partition gets its cloned FK
(parted_fk_naming_1_id_abc_fkey) as upstream expects.
The disabled foreign_key and rules tests are the only ones exercising FK
enforcement; all scheduled tests are unaffected.
- expected/constraints.out: regenerated for the now-working parted_fk_naming
section (opt-insensitive; opt=on falls back to this base file, which is
gitignored for _optimizer.out). Verified: constraints passes under BOTH
optimizer=on (203/203) and optimizer=off.
- init_file: mask the tablecmds.c line number in the generated test's
"found unexpected dependency type" error, which shifts on any edit to
tablecmds.c (this commit included).

…rift PG16 changed pg_get_viewdef so column references that are unambiguous are deparsed unqualified: a CTE star-expansion now emits 'SELECT e FROM cte' instead of 'SELECT cte.e FROM cte' (qp_with_functional), and view/function bodies emit 'id'/'fname' instead of 'people.id'/'people.fname' (variadic_parameters). This is a catalog->text deparse change, verified optimizer-independent (identical pg_get_viewdef under optimizer=on and off), so it affects the shared base .out for both the planner and ORCA matrices. Regenerated the base .out for all three; the prior campaign misclassified qp_with_functional_* as non-deterministic stragglers. Verified green under both optimizer=on and optimizer=off.

… removed) PG16 removed the HAVE_UNIX_SOCKETS configure macro -- Unix-domain sockets are now supported unconditionally. GGDB code still guarded AF_UNIX handling with #ifdef HAVE_UNIX_SOCKETS, so those branches silently compiled out. The critical case is internal_client_authentication() in auth.c: the entry-DB / QE-at-the-coordinator [local] bypass was inside the guard, so an internal connection arriving over the unix socket (its startup protocol carries the GPDB internal 0x7000 bit -- e.g. an entry-DB forked for a query touching a temp table plus a function) fell through to the reject branch and was denied by pg_hba. This broke gp_connections' internal-connection test with 'failed to acquire resources ... pg_hba.conf rejects connection for host "[local]"'. Removed the now-dead guards so AF_UNIX is handled unconditionally, matching upstream PG16 and the PG15 behavior. The other three sites (cdbutil.c, ic_udpifc.c, pgstat.c) are benign 'ignore AF_UNIX addresses' skips in getaddrinfo loops, cleaned up for the same reason.

…t status The PG16 merge reworked pg_regress's result reporting and erroneously made a non-zero psql child exit status fail the test outright, before even checking the output diff. Upstream pg_regress and the PG15 (cm3) code decide pass/fail from the output diff alone and only *log* a non-zero exit status. Some Greenplum tests intentionally make psql exit non-zero -- e.g. gp_connections ends by \connect'ing to a primary segment, which is rejected on purpose, leaving psql with no connection and an exit code of 2. Such tests were spuriously reported as failed even when their output matched the expected file (empty regression.diffs but 'not ok'). Restored diff-only pass/fail at both result-reporting sites, keeping the GPDB 'ignore:'-line downgrade and still logging the child exit status.
