I was about to make the same complaint as Heikki. We currently have two
different ways of dealing with this type of scenario:
DROP IF EXISTS (for most object types)
CREATE OR REPLACE (for functions, rules, views)
The OP wants to introduce yet a third variant, implemented for only one
kind of object. That's not a feature, it's a wart.
Clearly DROP IF EXISTS isn't helpful for the proposed use-case (since
you'd lose any pre-existing functions in the language) but I don't see
why CREATE OR REPLACE wouldn't serve.
