Read up on it at: http://www.postgresql.org/docs/8.1/static/maintenance.html#AUTOVACUUM Basically you need to turn on some stats stuff so autovacuum can determine when to run (in postgresql.conf): stats_start_collector = on stats_row_level = on And you need to enable autovacuum (in postgresql.conf): autovacuum = on autovacuum_naptime = 300 # time between autovacuum runs, in secs Then you can tune it if you need to but at least it will be looking for things that are vacuumworthy every 5 minutes.
