max_fsm_pages = 20000 max_fsm_relations = 1000 I just poked through the cluster. I have 6 user databases plus template0 and template1. Total tables in the cluster has reached slightly over 1,000 user tables plus all the system tables in the 8 databases. Does this indicate that I need to increase max_fsm_relations to greater than the total number of tables in the cluster? If so it's not a problem as bumping it to 2000 will only cost me ~50k of my 4G memory plus a bit more since max_fsm_pages would have to be increased to at least 32000. > Also you might want to check for newer versions of autovacuum.

I thought that bug was in some release prior to 7.4.6. Does the bug allow it to show a vacuum taking place but not do it?
