Vacuum (cron or auto) has no impact on the problem for 8.1beta3.
Tom had mentioned running oprofile, but I'm unable to get either 0.9.1 or 0.9.0
versions of oprofile working, so looks like I'll have to get a reproducible test

Anyone know of a script that can replay a PostgreSQL log file? Then I could log
all queries, wait till the problem hits, and then replay to see if that
reproduces it...
