In my previous post I failed to mention that after we stopped the applications and found that autovacuum remained idle for several minutes, we restarted postgres before cleaning up the bloat on the problem table. Also, the log shows that autovacuum stopped kicking in after 4:43 p.m. on Friday. It was at about this point that I was dropping and creating indexes through psql. I did not use BEGIN TRANSACTION, but I went home with an index being built on a large table, so that connection remained open until Sunday at 9:00 p.m. I don't know if that matters, but I'm trying to be thorough. -Kevin ---------------------------(end of broadcast)--------------------------- TIP 6: explain analyze is your friend
