Any chance you can get a backtrace from a build with debug symbols? The problem is that we haven't been able to reproduce the bug in testing. Like I said, it only seems to happen occasionally ... like maybe once in 10 or 20 (or more?) autovacuums. We've never been seen it with a manual vacuum at all. And we can't rebuild the production servers. -- -- Josh Berkus PostgreSQL Experts Inc. http://www.pgexperts.com
