What version of PostgreSQL are you running and on what type of hardware?

I suspect that moving pg_log onto a separate spindle and/or upgrading
your RAID controller to something with a BBU and configured in
write-back mode would get most of your performance back.

If you aren't running PostgreSQL 8.3, that might also help update
performance significantly as well.
