Full unfiltered PostgreSQL WordPress PHPUnit now passes locally in about 19 minutes. Use PostgreSQL setup and wrapper shortcuts, metadata and introspection caching, and shared-read savepoint reuse while preserving error isolation. Quick benchmark baseline is available under /tmp/cao-logs/sqlite-database-integration/full-suite-runtime-optimization-701531c/quick-benchmark-prepare-revision/.
Support MySQL SHOW COLLATION and SHOW DATABASES/SCHEMAS in the PostgreSQL driver using tokenized statement parsing and static MySQL-shaped result rows.
