Hi, I'm just wondering if autovacuum is ever supposed to vacuum the entire database during one of its runs. As far as I remember, it's supposed to vacuum one table at a time, based on the autovacuum_vacuum_threshold, autovacuum_analyze_threshold, etc. settings. For some reason, autovacuum decided to run a vacuum on my entire database (29GB large), and it's taking forever: select now(), query_start, current_query, backend_start, procpid, usename from pg_stat_activity where current_query <> '<IDLE>'; now | query_start | current_query | backend_start | procpid | usename -------------------------------+------------------------------- +---------------+-------------------------------+---------+---------- 2007-04-15 06:34:27.925042-07 | 2007-04-14 22:23:31.283894-07 | VACUUM | 2007-04-14 22:23:31.274121-07 | 9406 | postgres Is this expected behavior? --Richard
