You can do it, if you're into pain ;-). In the first place, there are quite a lot of features in 8.4 that aren't in 8.1. So you'll be frequently tripping over stuff that works fine in your devel environment and fails when you put it in production. The same goes from a performance standpoint: some queries that perform well in 8.4 won't in 8.1. And lastly, 8.1 will be EOL'd and no longer supported by the end of this year. So you really need to be thinking about migrating your production DB to something newer, anyway. http://wiki.postgresql.org/wiki/PostgreSQL_Release_Support_Policy regards, tom lane -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
