I thought about DROP DATABASE, but wasn't sure if it would clean up EVERYTHING. I had a bad experience early this year when I restored a database that was running on Postgres 7.x.x. The database crashed badly, that I couldn't recover it. It ended up that I had to restore it from a previous night's backup. I noticed a huge decrease in performance after the restore. I always have thought that there was something that hasn't been cleaned up (Yes, I did run the VACUUM command). I decided not to investigate it anymore, because I already had a plan to upgrade to 8.3.8 anyway. I assume most of you would just do the DROP DATABASE for the scenario that I described. Is that correct?

Removing the data directory removes the whole Postgres cluster, possibly including the config files. -- Adrian Klaver adrian.klaver@xxxxxxxxx -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
