Actually, now that I look at it, there is a non-cosmetic issue here:
we seem to be creating a dependency link for the pg_class owner field.
We have to either not do that, or be willing to fix it during ALTER TYPE
OWNER.  For instance

regression=# create user foo;
CREATE ROLE
regression=# create user bar;
CREATE ROLE
regression=# \c - foo
You are now connected as new user "foo".
regression=> create type mytype as (f1 int);
CREATE TYPE
regression=> \c - postgres
You are now connected as new user "postgres".
regression=# drop user foo;
ERROR:  role "foo" cannot be dropped because some objects depend on it
DETAIL:  owner of composite type mytype
owner of type mytype
regression=# alter type mytype owner to bar;
ALTER TYPE
regression=# drop user foo;
ERROR:  role "foo" cannot be dropped because some objects depend on it
DETAIL:  owner of composite type mytype
regression=#

            regards, tom lane

This is exactly what I did that led me to discover this issue. I need
to drop a user but I can't because some objects depend on it. The only
way around it is to delete the type and everything else that depends on
it and recreate it and its dependents as the new owner of the type.
What a pain....
