Bug in ALTER TABLE/SEQUENCE OWNER TO

I discovered the following confusing issue in CVS HEAD:

CREATE TABLE test(id SERIAL NOT NULL);
ALTER TABLE TEST OWNER TO testuser;

SELECT typname, typowner, relname, relowner from pg_type c JOIN pg_class d
ON (d.reltype = c.oid) WHERE typname = 'test';

typname | typowner | relname | relowner
---------+----------+---------+----------
test | 10 | test | 16419

SELECT typname, typowner, relname, relowner from pg_type c JOIN pg_class d
ON (d.reltype = c.oid) WHERE typname = 'test_id_seq';
typname | typowner | relname | relowner
-------------+----------+-------------+----------
test_id_seq | 10 | test_id_seq | 16419
(1 row)

As you can see, the owner of the sequence and table row type isn't changed
as well. I have done a small patch that adresses this issue for discussion.
Please note that it breaks the dependency regression test at least:

ALTER TABLE deptest OWNER TO regression_user3;
DROP USER regression_user3;
ERROR: role "regression_user3" cannot be dropped because some objects
depend on it
! DETAIL: owner of table deptest
-- if we drop the object, we can drop the user too
DROP TABLE deptest;
DROP USER regression_user3;
--- 33,40 ----
ALTER TABLE deptest OWNER TO regression_user3;
DROP USER regression_user3;
ERROR: role "regression_user3" cannot be dropped because some objects
depend on it
! DETAIL: owner of type deptest
! owner of table deptest
-- if we drop the object, we can drop the user too
DROP TABLE deptest;
DROP USER regression_user3;

Any opinions?
