Postgres 19 delayed after AI reviewers find more bugs than humans can fix

Postgres is the week's cleanest measurement of what cheap detection costs downstream. GA moved to about November 19, 2026 and 8 to 10 significant features went back to PG20, after LLM-assisted review produced about 40 reports averaging a three-line fix. The quality bar rose after the features were written and committed, so finished work became work in doubt. Grant review and PHP's patch race follow the same pattern with different people absorbing the load. Watch PG20, which was expected to be bug-fix-only and now carries the leftovers; a verifier only pays off if remediation capacity grows to match.
