Good morning, this is your PostgreSQL briefing for June 6th, 2026.
Today's activity centers on critical stability fixes, with several commits addressing bugs that could lead to data corruption, crashes, or incorrect query results.
The most significant fix tackles tuple deformation with virtual generated columns. Commit 89eafad resolves a fundamental issue where the tuple descriptor finalization process failed to account for virtual generated columns, which are always stored as null in tuples. This could result in incorrect attribute cache…
Memory safety also received attention with two notable fixes. The pg_surgery extension had an off-by-one bug in heap offset handling that could write past array boundaries and crash the server. Meanwhile, a separate commit addressed message truncation in pg_stat_activity when transaction IDs grew large, fixing a…
Plan caching problems in the refint module prompted a more dramatic solution. Rather than patch multiple bugs in the per-backend plan cache—including issues where cached plans reused old parameter values and never invalidated stale entries—developers removed the cache entirely. Since refint serves primarily as…
