Apologies if this is old news, but pg_autovacuum in 8.0.x has the bad habit of SEGVing and exiting when a table gets dropped out from under it. This creates problems if you rely on pg_autovacuum for the bulk of your vacuuming as it forgets it's statistics when it is restarted and so will skip some desireable vacuums.
I have a patch for this that should apply against any 8.0.x if there is any interest. I looked at the new autovacuum in 8.1 and it appears from casual inspection not to have the same problem. -dg -- David Gould [EMAIL PROTECTED] If simplicity worked, the world would be overrun with insects. ---------------------------(end of broadcast)--------------------------- TIP 4: Have you searched our list archives? http://archives.postgresql.org
