The largest table in my database (30GB) has mysteriously went from taking

a 4GB shared_memory. Could this slow down have to do with the fsm_max_pages
or something else like that? I made it larger but the queries still taking a
long time. I do daily vacuum's but I don't run it with -z or --full. I
would like to avoid doing a --full if possible because it would literally
take over a week to complete. Any help would be greatly appreciated.
Benjamin,
When is the last time you ran ANALYZE? That's what the -z option does. If
you're only vacuuming once daily, you should definitely analyze with the -z
flag as well.
