I don't understand why you think you need the CREATE OR REPLACE FUNCTION
commands?  We only need to change proargtypes, and the updates did that.
The catcache can take care of itself.

I think it would be good practice to be more careful about
schema-qualifying all the pg_catalog table and type names.

I also think it's a bad idea to use to_regprocedure() rather than
a cast to regprocedure.  If the name isn't found, we want an error,
not a silent NULL result leading to no update occurring.
