Hello, it's October 16th, 2026, and this is your PostgreSQL daily briefing.
The lead signal today is correctness in rare but serious edge cases, where normal queries or admin commands could fail or return wrong results without warning.
First, silent wrong answers. Commit ba 51 d 62 fixes parallel T I D range scans reusing the wrong block range on rescan. If a rescan used a different row identifier range, such as inside a correlated subquery, rows were quietly skipped. The fix resets that shared range state, so each rescan starts fresh. Related,…
Second, operations and observability. Commit a 39 e 53 fixes Drop Database Force failing when parallel autovacuum workers were running. A non-superuser with permission to stop background tasks was denied stopping those parallel workers because they advertised the wrong role. The fix checks against the leader's role.…
Finally, hardening foundations. Commit 29 4 d 21 9 centralizes how psql labels its hidden queries behind a new comment helper, setting up a safe gate for translation that could otherwise break under mismatched encodings. Commit 30 d 4 a 6 modernizes XML content parsing to drop a deprecated libxml feature and…
