- AsyncPG: remove dead execution helpers, use singleton RNG and exception chain depth limit, optimize connection pool configs and ADK session round-trips. - Psycopg: simplify connection and driver hierarchy, remove dead passthrough methods, add typed query conversion helper without byte encoding, streamline ADK and Litestar session stores. - PsqlPy: remove obsolete driver wrappers and query cache indirection, consolidate connection pool configs, optimize Arrow conversion helpers. - CockroachDB (AsyncPG & Psycopg): inherit from PostgreSQL base driver and exception handlers, fix follower read transaction commit leak, specialize data dictionaries with per-connection version caching, align multi-region configuration options.

Reduce ADK store round trips with RETURNING, bound psycopg COPY buffering, and release failed psqlpy initialization attempts. Preserve native PostgreSQL configuration controls and quoted typing boundaries.
The psqlpy pipeline optimization remains deferred pending cancellation, preflight, and error-attribution fixes. Schema metadata caching remains deferred until DDL/search-path invalidation is defined. No gateway_region connection option is advertised; it is not a supported session setting.
Validation: 10 focused no-service native-option and cancellation tests passed; scoped Pyright reported 0 errors; scoped Ruff and git diff --check passed. Database-service integration, native compiled-wheel behavior, and documentation builds were not run locally. Hosted CI supplies the broader validation boundary.
A previous hosted integration attempt stopped before tests when Docker timed out contacting
https://icr.io/v2/while pulling a service image. This is an infrastructure validation block; no passing integration result is claimed.Rebase validation: based on main
a1067c856, with branch source changes preserved. Reconciled changelog entries, checked release-history preservation, and passed the focused documentation audit and whitespace checks. No runtime suites were rerun for this documentation-only update.CI repair: register the consumed BigQuery
storage_write_stream_typesetting in the shared feature contract (exact regression passed). Docker pre-pulls retry up to three times with bounded backoff and preserve failure after exhaustion. YAML, shell syntax, scoped zizmor, and fake-command success/retry/failure checks passed. No local database services or broad test suites were run. Fresh hosted checks are pending on the updated head.
