From Jan–Sep 2026, we worked upstream with @postgresql.org to ship PG 20 queryable conflict tables, O(1) CheckXidAlive scans, superuser-free LO pg_dump & fixes across plpgsql_check, pgfincore & pgtt. Read & tell us which patch you're testing: goo.gle/postgresql-2...

Slide 01/04 of a dark-themed Google Open Source technical carousel titled "UPSTREAM ENGINEERING // POSTGRESQL 20: Shipping PostgreSQL 20: Inside Our 2026 Upstream Core & Extension Fixes." Subtitle: "From queryable logical replication conflict tables to single-check sequential scans and superuser-free pg_dump on Large Objects." Features a group photograph of attendees at Postgres Bangalore (PGBLR) Meetup 10 alongside the Google Cloud PostgreSQL engineering team, credited to Dilip Kumar (PostgreSQL Significant Contributor) with Nitin Motiani, Robert Pang, Aniket Jha, and Sunaina Punyani. Footer: opensource.googleblog.com • goo.gle/postgresql-2026-highlights.

Slide 02/04 titled "LOGICAL REPLICATION & ACCESS CONTROL: Queryable Conflict Logs & Superuser-Free Large Objects." Displays two dark terminal windows with syntax-highlighted SQL. Terminal 1 ("psql — Logical Replication (PostgreSQL 20 Roadmap)") shows: CREATE SUBSCRIPTION prod_active_sub CONNECTION 'host=primary.db dbname=prod' PUBLICATION core_tables_pub WITH (conflict_log_destination = 'table'); followed by SELECT relid, conflict_type, remote_xid FROM pg_conflict.pg_conflict_log_'%sublid%';. Terminal 2 ("upstream_patches.sql — Least-Privilege & Concurrency") shows: GRANT pg_read_all_data TO backup_role; (enabling superuser-free pg_dump on Large Objects) and REINDEX TABLE CONCURRENTLY orders_with_deferrable_pk; (preserving DEFERRABLE constraint semantics across rebuilds via INDEX_CREATE_DEFERRABLE).

Slide 03/04 titled "SCAN OPTIMIZATION & ECOSYSTEM FIXES: Core Scan Optimization & Ecosystem Memory Safety." Top callout banner ("CORE ENGINE OPTIMIZATION (TABLE_SCAN_NEXT)") reads: "CheckXidAlive: N Tuple Checks -> 1 Check/Scan — Eliminates redundant per-tuple transaction liveness checks in table_scan_next() by verifying CheckXidAlive once per sequential scan." Below is a 2x2 technical fix matrix: (1) STANDBY PROMOTION: pg_promote() Timeout Fix (fixed premature standby promotion timeouts under heavy load); (2) DSM HASH CLEANUP: dshash Detach Segfault (prevented segmentation faults when processes exit after FATAL); (3) PLPGSQL_CHECK & PGTT: PG14 LWLock & UAF Fixes (added shmem_request_hook LWLock registration & deep-copied plans); and (4) PGFINCORE PR #12 & #13: Buffer & Pointer Safety (fixed off-by-one buffer check and dangling pointer dereference).

Slide 04/04 titled "COMMUNITY & ECOSYSTEM // @OPENSOURCE.GOOGLE: Built Upstream With the PostgreSQL Community." Box 1 ("UPSTREAM PROJECTS & MAINTAINERS") credits Core Engine: PostgreSQL Global Dev Group (@postgresql.org), plpgsql_check: Pavel Stehule (okbob/plpgsql_check), pgfincore: Cédric Villemain (klando/pgfincore — PR #12 & #13), and pgtt: Gilles Darold (darold/pgtt — Global Temp Tables). Box 2 ("UPSTREAM ROADMAP & COMMUNITY DISCUSSIONS (PGSQL-HACKERS)") lists Conflict Resolution (auto-resolving via PG 20 conflict tables), Active-Active Replication (multi-master conflict logging foundation), Extension Hardening (plpgsql_check, pgfincore & pgtt patches), and Get Involved (test patches & share feedback on pgsql-hackers).
