Good morning. It's August 4th, 2026, and this is your PostgreSQL briefing.
The theme running through today's commits is enforcement catching up to intent. Several fixes close gaps between what Postgres is supposed to do and what it actually did in edge cases, and most trace back to review from Noah Misch.
Start with property graphs. Commit fa62d4f, from Peter Eisentraut, prohibits using GRANT ON TABLE against a property graph, closing off a compatibility path that was never meant to apply there, and fixing missing access-control cases in the grant machinery. A companion doc fix, 63c3bbb, adds property graphs to the…
Second theme: shared catalog locking. Jeff Davis has two related fixes here. Commit b66ea17 improves how DROP SERVER handles dependent subscriptions, generalizing deletion-lock handling for shared catalogs and adding a clearer hint when a subscription blocks the drop. Commit b48caa7 fixes a related gap from an…
Third theme: replication and data safety under real-world conditions. Amit Kapila's commit a3fed76 moves the check for retain_dead_tuples compatibility from DDL time into the apply worker itself, fixing a pg_upgrade failure when the publisher isn't reachable, and…
