ALTER TABLE ... OWNER TO does not change ownership recursively

It seems that ALTER TABLE ... OWNER TO does not change the ownership of
any inheriting tables. The documentation states:

> If ONLY is specified, only that table is altered. If ONLY is not
> specified, the table and any descendant tables are altered.

Which to me indicates that ownership should be altered on the target table and
any descendant tables as well.

Here is a small test case to reproduce the problem:

create table parent (id int);
create table child () inherits (parent);
create role new_owner;
alter table parent owner to new_owner;

After performing this sequence of commands, \d looks like:
 Schema |     Name      |   Type   |   Owner
--------+---------------+----------+-----------
 public | child         | table    | ryan
 public | parent        | table    | new_owner

But I would expect that without specifying only, I would get:
 Schema |     Name      |   Type   |   Owner
--------+---------------+----------+-----------
 public | child         | table    | new_owner
 public | parent        | table    | new_owner

Attached is a patch which fixes this issue. It is based off of REL8_4_11.
