+1 here. Even more than "autovacuum vacuumed table x", I'd like to see "vacuum starting table x" and "vacuum done table x". The reason I say that is because the speculation "autovacuum might have been running" is now a frequent phrase I hear when performance questions are asked. If vacuum start and end times were logged at a much earlier level, that feature plus log_min_duration_statement could easily disprove the "vacuum might have been running" hypothesis. ---------------------------(end of broadcast)--------------------------- TIP 5: don't forget to increase your free space map settings
