Yeah, the ALTER LARGE OBJECT page could use improvement.  The correct
general rule is explained in section 5.6:

    An object can be assigned to a new owner with an ALTER command of the
    appropriate kind for the object, e.g. ALTER TABLE. Superusers can
    always do this; ordinary roles can only do it if they are both the
    current owner of the object (or a member of the owning role) and a
    member of the new owning role.

Most other ALTER-something pages have wording like "To alter the owner,
you must also be a direct or indirect member of the new owning role",
but this seems to have been missed in the ALTER LARGE OBJECT docs.
