SQL code versioning (views, functions, etc) - Mailing list pgsql-admin

Hi all you pg gurus and admins,

   I'm trying to implement versioning of the code of objects that can be
"created or replaced" (functions, views, etc).

   I tried to implement a trigger on pg_proc, but that is not possible.
Adding a rule to the pg_proc table was successful but it never executes.

   Is there a way or a tool to implement versioning of the code of this
objects? Help or hints will be gladly appreciated.

Cheers,
