Some time ago I reported a problem where right after an index rebuild vacuum might take a couple of hours, but gets slower and slower at a seeming increasing rate as time goes on. What takes a couple of ours after a full index rebuild now takes 12 hours or more. The problem was determined to be due to the fact that indexes are vacuumed in index order, not in disk storage order. I don't see anything about this in the "What's new" for 8.1. Has anything been done to resolve this? Scheduled index rebuilds are not feasible. I really don't even want to take a chance on starting one. The database is just a hair under one billion rows, and could take the entire weekend or more to rebuild. Wes
