[snip] A VACUUM FULL will correct the issue, but put the site out of commission for roughly 20 minutes as the drive crunches the information.
My question is, should the purging of rows be done more often then once a day for both tables. Is this why performance seems to take a hit specifically? As there were too many rows purged for vacuum to accurately keep track of?
ISTR that there are setting in postgresql.conf which affect how many tables/rows vacuum can reclaim. The docs say that the default setting of max_fsm_pages is 10000. Maybe this should be increased for your situation?
