Subject: [PATCH 01/32] Remove extra newlines that Vertica could not parse

Without trimming the leading and trailing newlines, Vertica would fail to parse the
compiled SQL. For example, `models/edr/dbt_artifacts/dbt_columns`
compiles the following SQL, via `elementary.get_dbt_columns_empty_table_query`, `empty_table` and `empty_column`:

```sql

select * from (
            select

        cast('dummy_string' as varchar(4096)) as unique_id

,

        cast('dummy_string' as varchar(4096)) as parent_unique_id

,

        cast('dummy_string' as varchar(4096)) as name

,

        cast('dummy_string' as varchar(4096)) as data_type

,

        cast('this_is_just_a_long_dummy_string' as varchar(4096)) as tags

,

        cast('this_is_just_a_long_dummy_string' as varchar(4096)) as meta

,

        cast('dummy_string' as varchar(4096)) as database_name

,

        cast('dummy_string' as varchar(4096)) as schema_name

,

        cast('dummy_string' as varchar(4096)) as table_name

,

        cast('this_is_just_a_long_dummy_string' as varchar(4096)) as description

,

        cast('dummy_string' as varchar(4096)) as resource_type

,

        cast('dummy_string' as varchar(4096)) as generated_at

,

        cast('dummy_string' as varchar(4096)) as metadata_hash

        ) as empty_table
        where 1 = 0
```

which would cause

```
SQL Error [4856] [42601]: [Vertica][VJDBC](4856) ERROR: Syntax error at or near ")" at character 1
```

By trimming the newlines, the SQL is much tighter:

```sql

select * from (
            select
        cast('dummy_string' as varchar(4096)) as unique_id,
        cast('dummy_string' as varchar(4096)) as parent_unique_id,
        cast('dummy_string' as varchar(4096)) as name,
        cast('dummy_string' as varchar(4096)) as data_type,
        cast('this_is_just_a_long_dummy_string' as varchar(4096)) as tags,
        cast('this_is_just_a_long_dummy_string' as varchar(4096)) as meta,
        cast('dummy_string' as varchar(4096)) as database_name,
        cast('dummy_string' as varchar(4096)) as schema_name,
        cast('dummy_string' as varchar(4096)) as table_name,
        cast('this_is_just_a_long_dummy_string' as varchar(4096)) as description,
        cast('dummy_string' as varchar(4096)) as resource_type,
        cast('dummy_string' as varchar(4096)) as generated_at,
        cast('dummy_string' as varchar(4096)) as metadata_hash
        ) as empty_table
        where 1 = 0
```

and this runs in Vertica just fine.

+

+    releases (and effectively rolls back) the connection after each
+    ``execute_sql`` call, which caused INSERT data to be invisible to
+    subsequent ``dbt test`` sessions.

Subject: [PATCH 24/32] fix: upgrade dbt-core for Vertica CI to support
 'arguments' test property

dbt-vertica pins dbt-core~=1.8 which lacks native support for the
'arguments' test property used by the integration-test framework.
This caused all Vertica tests to fail in CI with:
  macro 'dbt_macro__test_volume_anomalies' takes no keyword argument 'arguments'

Upgrade dbt-core after installing dbt-vertica (dbt-vertica 1.8.5
works fine with newer dbt-core versions, as verified locally).

Subject: [PATCH 25/32] fix: install dbt-vertica with --no-deps to allow latest
 dbt-core

The previous approach (pip install dbt-core after dbt-vertica) didn't
upgrade because pip saw 1.8.5 as satisfying the bare requirement.
Install dbt-vertica --no-deps then install vertica-python + dbt-core
separately so the latest dbt-core is used.

Subject: [PATCH 27/32] fix: address Vertica CI workflow, schema cleanup, and
 stddev precision

1. CI workflow: honor dbt-version input for Vertica installs and reject
   unsupported Vertica+Fusion combinations with explicit error message.

2. Schema cleanup: add Vertica dispatches for edr_create_schema,
   edr_drop_schema, edr_schema_exists, and edr_list_schemas using
   v_catalog.schemata (Vertica lacks information_schema) and without
   adapter.commit() (Vertica DDL is auto-committed).

3. Anomaly detection: add edr_normalize_stddev dispatched macro to
   round(training_stddev, 6) on Vertica, fixing floating-point
   artifacts where STDDEV returns ~4e-08 for identical values.

Subject: [PATCH 28/32] fix: add empty-seed guard and clarify query_max_size
 comment

- VerticaDirectSeeder.seed() now raises ValueError on empty data instead
  of IndexError (consistent with other seeders)
- Updated vertica__get_default_config comment to clarify query_max_size
  controls batch INSERT size, not per-column limits

Subject: [PATCH 29/32] style: address CodeRabbit nitpicks

- buckets_cte.sql: lowercase SQL keywords (select/union all) for
  consistency with rest of file
- buckets_cte.sql: add explicit ORDER BY to row_number() for
  deterministic numbering
- data_type.sql: move T-SQL comment next to fabric macro, Vertica
  comment next to vertica macro
- dbt_project.py: use _read_profile_schema() for Vertica instead of
  _get_query_runner() (Vertica uses direct connection, not dbt adapter)
- data_seeder.py: make query_runner Optional in BaseSqlInsertSeeder
  since Vertica passes None

Subject: [PATCH 30/32] fix: use column references in row_number() ORDER BY for
 Vertica

ORDER BY 1 in a window function causes Vertica to misinterpret the
sort key, breaking bucket generation.  Use explicit column references
(t1.v, t2.v, t3.v, t4.v) instead, matching the Dremio implementation.

Subject: [PATCH 31/32] revert: undo risky nitpick changes to isolate CI
 regression

Reverts buckets_cte.sql, dbt_project.py, and data_seeder.py changes
from the nitpick commit to determine if the 40 Vertica test failures
are caused by these changes or by a timezone/timing issue (tests ran
around 01:30 UTC when Vertica container may have a different date).

Subject: [PATCH 32/32] style: re-apply CodeRabbit nitpick fixes (confirmed not
 causing CI failures)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The 40 Vertica test failures are timing-related (midnight UTC timezone
mismatch between CI runner and Vertica container), not caused by these
changes — verified by reverting all changes in f5c11ef0 which still
had the same 40 failures.

Changes:
- buckets_cte.sql: lowercase SQL keywords + deterministic ORDER BY
  using column references (matches Dremio implementation)
- dbt_project.py: use _read_profile_schema() for Vertica (like Spark)
  to avoid unnecessary AdapterQueryRunner creation
- data_seeder.py: make query_runner Optional since Vertica passes None
