On the off-chance that you haven't seen these docs yet, here are links
to fine tuning your postgresql settings:
http://www.varlena.com/varlena/GeneralBits/Tidbits/perf.html
http://www.varlena.com/varlena/GeneralBits/Tidbits/annotated_conf_e.html
And remember that you should VACUUM FULL ANALYZE your database regularly
(more often if there are a lot of updates/deletes). If this hasn't been
performed recenlty you would probably notice a large performance
increase after running it.
