Well, you have DROP [IF EXISTS] which should cover at least some of the use cases. I'm not sure a OR REPLACE for aggreates is a good idea -- you can already REPLACE the internal function (which is mostly what you need). The aggregate itself mainly defines the input types, state, and output types. The main advantage of replace is you get to preserve the oid and avoid dependency issues -- if you are changing the aggregate, it's pretty likely you'd have to go through that anyways. merlin -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
