Either (1) do nothing (reject this whole proposal) or (2) put hstore
in core where it will have a well-known OID. While it would be nice to
have some more-workable way to interconnect independent extensions,
I feel no need to either design a solution to that on the spot, or to
accept half-baked approaches to it.
