Changing ownership of simple composite incomplete?

Hackers;

I spotted this after doing some owner reassignments and then dropping
the old roles.

It looks like using either reassign or alter type owner to, the pg_class
entry stays with old rolID.

Then if we drop that old role going forward pg_dump complains about
invalid owner.

See below test case. I did look at releast notes above 9.4 and didn't
notice a fix. I observed the problem originally on a 9.1 system here.

And the warning is a bit confusing since it says "table" rather than type.

FYI Thanks

$ cat q
\set ON_ERROR_STOP

begin;

select version();

create role foo;
create schema foo;
set search_path to foo;

prepare foo as
select c.relowner, t.typowner
from pg_class c
join pg_type t on typrelid = c.oid
and typname = 'foo';

create type foo as (a int);

execute foo;

alter type foo owner to foo;

execute foo;

reassign owned by foo to postgres;
drop role foo;

execute foo;

alter type foo owner to postgres;

execute foo;

commit;

\! pg_dump --schema-only --schema foo >/dev/null
\echo '^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^\n\n\n'

drop schema foo cascade;
