I've been digging around in the code and found where we are executing the VACUUM command. VACUUM ANALYZE is executed every 15 minutes. We haven't tried VACUUM FULL ANALYZE. I think I read that using FULL is a good idea once a day or something. Just doing a VACUUM ANALYZE doesn't seem to be preventing our problem. Thank you for the responses.
