Correct.

Right, there is a narrow hack in CREATE TRIGGER that does that to allow
loading of existing dump scripts. But I think what Terry is trying to
do is modify an existing trigger function with

CREATE OR REPLACE trigfunc() RETURNS OPAQUE AS ...

and the system won't (and shouldn't) let him change the function return
type back to OPAQUE.

The only answer is to replace OPAQUE by TRIGGER in your function
scripts.
