If all of those sessions are truly doing a select count(*) from a .75
million row table (plus half a million dead rows), then I'm not suprised
it's bogged down. Every query has to loop through the cache of the full
table in memory every time it's run.
Your CPU is doing something. I doubt that postgresql.conf settings are
going to help. What exactly are all those high CPU usage sessions doing?
