Heikki Linnakangas ff8f27d6ea Don't allow composite type to be member of itself via multirange
CheckAttributeType() checks that a composite type is not made a member
of itself with ALTER TABLE ADD COLUMN or ALTER TYPE ADD ATTRIBUTE,
even indirectly via a domain, array, another composite type or a range
type. But it missed checking for multiranges. That was a simple
oversight when multiranges were added.
