That isn't how it works. The naptime is per database, not per cluster. If the naptime is 1 minute and there are 50 "active" databases, then it will launch a new worker every 1.2 seconds (assuming the old ones finish fast enough that doing so would not exceed autovacuum_max_workers) Cheers, Jeff -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
