Hi,The largest table in my database (30GB) has mysteriously went from taking milli-seconds to perform a query to minutes. This disks are fine and I have 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
