Buffer overflow risk in mysql_real_escape_string: All 7 PgSQL test files used fixed 256-byte buffers for escaped credentials.

NULL dereference in polling loops: mysql_store_result() can return NULL, and calling mysql_fetch_row(NULL) is undefined behavior. Added NULL checks in all verify_pg_digest(), poll_pg_digest_count(), verify_digest(), and poll_digest_count() polling loops across both PgSQL and MySQL test files. In loop contexts, uses continue; in non-loop contexts, uses conditional fetch (res ? fetch(res) : NULL). Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>	3 months ago

PROTOCOL_VERSION macro conflict: pg_lite_client.h defines PROTOCOL_VERSION as a static const int, but mariadb_version.h (included via mysql.h) defines it as a preprocessor macro (#define PROTOCOL_VERSION 10).

MYSQL_QUERY in void function: The clear_pg_stats() helper is a void function, but MYSQL_QUERY macro expands to "return EXIT_FAILURE" on error, which doesn't compile in a void context.

Address AI code review feedback on PgSQL FFTO tests (#5517 )

Fixes from Copilot and CodeRabbit reviews on PR #5526:

1. Buffer overflow risk in mysql_real_escape_string: All 7 PgSQL test
   files used fixed 256-byte buffers for escaped credentials. Changed
   to VLAs sized from strlen() (2*len+1), matching the safe pattern
   used in the existing test_ffto_pgsql-t.cpp.

2. NULL dereference in polling loops: mysql_store_result() can return
   NULL, and calling mysql_fetch_row(NULL) is undefined behavior.
   Added NULL checks in all verify_pg_digest(), poll_pg_digest_count(),
   verify_digest(), and poll_digest_count() polling loops across both
   PgSQL and MySQL test files. In loop contexts, uses continue; in
   non-loop contexts, uses conditional fetch (res ? fetch(res) : NULL).

Fix build issues in PgSQL FFTO E2E tests (#5517 )

Two build issues fixed across all 7 PgSQL FFTO test files:

1. PROTOCOL_VERSION macro conflict: pg_lite_client.h defines
   PROTOCOL_VERSION as a static const int, but mariadb_version.h
   (included via mysql.h) defines it as a preprocessor macro (#define
   PROTOCOL_VERSION 10). Fixed by including pg_lite_client.h before
   mysql.h in the two tests that use it.

2. MYSQL_QUERY in void function: The clear_pg_stats() helper is a
   void function, but MYSQL_QUERY macro expands to
   "return EXIT_FAILURE" on error, which doesn't compile in a void
   context. Fixed by using mysql_query() directly instead of the
   MYSQL_QUERY macro in all clear_pg_stats() definitions.

FFTO E2E TAP test: PostgreSQL large result sets (#5517 )

Add test_ffto_pgsql_large_resultsets-t.cpp covering FFTO behavior with
large PostgreSQL result sets. Part of the comprehensive PgSQL E2E test
suite for issue #5517.

Test scenarios (13 TAP assertions):
1. SELECT returning 10,000 rows via generate_series — verifies
   sum_rows_sent accuracy through PgSQLFFTO's CommandComplete tag
   parsing ("SELECT 10000").
2. SELECT with ~1 KB TEXT columns (50 rows) — validates row counting
   with large per-row payloads under FFTO buffer management.
3. Result set under ffto_max_buffer_size (64 KB) — confirms FFTO
   stays active and records digests when within threshold.
4. Bulk INSERT of 500 rows via generate_series — validates
   sum_rows_affected tracking from "INSERT 0 500" tag.

Uses the PgSQL FFTO test pattern: MySQL admin connection for config
and stats queries, libpq PGconn for data operations, stats cleared
via stats_pgsql_query_digest_reset, verify_pg_digest() with polling.
