Greetings,
I've just run up against a problem with ALTER LANGUAGE ... OWNER
TO ... wherein the change of ownership does not propagate to a
language's handler and validator functions preventing you from
dropping the role if it created a language. I'm assuming a valid
workaround is manually change the owner of the handler and validator
functions but I'd think that changing a languages owning role should
propagate to any other objects created when the language was created.
Here's my test case. I haven't posted this as an official bug report
as I'm not sure if this should be called a bug or simply not
implemented convenience behavior (i.e. a feature request).
$ psql -U postgres
Password for user postgres:
Null display is "\N".
