Did you analyze after you imported the dump?

The actual upgrade went pretty well. However my application is now getting >10 times slower INSERT times than it was under 7.3.2. As far as possible I mirrored the settings in postgresql.conf (obviously I couldn't just drop in the old config). Any thoughts as to where to look, or what to do to fix this? Thanks, David. ---------------------------(end of broadcast)--------------------------- TIP 3: Have you checked our extensive FAQ? http://www.postgresql.org/docs/faq
