We vacuum analyze nightly, and vacuum normally ad-hoc (but we're going to schedule this weekly moving forward).
Interesting pointer about system catalog bloat. I tried to vacuum full the system catalog tables (pg_*), and the performance for creating a single table manually improved dramatically (back to what it used to be), but as soon as I created the next schema, the performance went back down to the same level. So there's a clue there somewhere. Next I will try to vacuum full the entire database. -----Original Message----- From: Tom Lane [mailto:t...@sss.pgh.pa.us] Sent: Saturday, November 07, 2009 10:29 PM To: Aris Samad-Yahaya Cc: pgsql-performance@postgresql.org Subject: Re: [PERFORM] CREATE TABLE slowing down significantly over time "Aris Samad-Yahaya" <a...@quickschools.com> writes: > I'm facing a problem where running a CREATE TABLE has slowed down > significantly over time. System catalog bloat maybe?
