PostgreSQL: Weekly Recap - Hardening Privileges and Edge-Case Reliability
30 commits this week focused on hardening rather than features, with fixes for privilege checks, repack safety, and monitoring accuracy. The pattern is closing silent gaps where restores dropped statistics, permissions diverged, or rare row shapes caused failures.

This week saw 0 pull request activity items, 30 additional commits this week.
Our lead insight: this was a hardening week with no new features, focused on rare corruption paths, privilege gaps, and misleading monitoring that affect production operators.
First, correctness in edge cases. Concurrent repack could fail or crash when processing old row versions created before a column was added without a rewrite, covered in commit 45da2c1. The worker decoded changes with a temporary table description that lacked missing defaults, turning absent values into nulls and…
Second, closing privilege gaps. Foreign key checks in commit 1a846a5 now verify execute permission for the equality and type conversion functions used by the fast validation path, matching the slower path. Without this, a user could bypass function permission checks during bulk constraint validation. Separately, the…
Third, maintainability cleanup. Commit 0e0bf0d replaces a custom 64-bit object identifier format marker with a portable standard format to avoid breaking translated messages. Commit 16a1040 declares variable-length…
