fix: Correct PostgreSQL accelerator connection pool parameter name and defaults (#1528)

* fix: Add nanosecond timestamp range limitation to MSSQL and Oracle versioned docs

Commit d5341c4 documented the Arrow nanosecond timestamp range
limitation (~1677–2262) for MSSQL and Oracle connectors, but only
in website/docs/ (vNext). The limitation existed in all prior versions
too — in versions 1.5.x–1.11.x, out-of-range timestamps silently
returned 1970-01-01 UTC instead of erroring.

Propagate the limitation note to all 7 versioned doc directories
(14 files total) with version-appropriate wording.

* fix: Correct PostgreSQL accelerator connection pool parameter name and defaults

The docs listed pg_connection_pool_min_idle (default 1) and connection_pool_size
(default 5), but the code uses pg_connection_pool_min (default 5) and
connection_pool_size (default 10).
