Alvaro, Scott - thanks for your replies and the direction you pointed me into. The underlying problem was that the cost limit was too low, so the autovacuum process would run forever and not be able to do anything. I reduced the cost delay and increased the cost limit form the default of 200 to 10000, which is slightly more than the longest time I saw when running manually. Autovacuum now works as expected - the tables, which have a very high rate of updates and some inserts (very few) are not growing anymore. The run time for the scheduled background processes (which perform some background aggregation) have gone down slightly (about 10%) as well. Since autovacuum will prevent a deadlock, it is definitely preferable to me over manually vacuuming. Once again, thanks! -- Sent via pgsql-admin mailing list (pgsql-admin@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
