Just to double-check, make sure stats_start_collector and stats_row_level are on, and confirm that you see the stats collector process in "ps". Also, do you have any of the autovac threshold parameters at nondefault values? The autovac process doesn't run continuously, so not seeing it in ps is not proof that there's a problem. But if pg_stat_all_tables isn't showing any evidence of vacuums happening, that's probably bad. > So if it is running after all, how can I track down why things aren't > getting vacuumed? What log level are the autovacuum logs at? I think you've gotta crank it up to DEBUG2 or so, which is gonna be noisy :-( regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 2: Don't 'kill -9' the postmaster
