First of all - this is not a bug, so please don't report it as a bug. Second of all - did you read this part of documentation: http://www.postgresql.org/docs/8.3/interactive/maintenance.html Best regards, depesz

My question is how frequently weneed to run those commands(commands for db maintainance). how frequently do you need to do file system maintenance? or for that matter, how often do you have to wash your car? the answer, my friends, is it depends on far too many factors for a generic answer. with autovacumn in place and with your database reasonably well tuned to your application requirements, there may be NO need for scheduled regular maintenance, other than backups. but, again, this would far better be discussed on the -general or -admin email lists, not on -bugs.
