Thank you for checking that.  Teodor's goal was that new-hstore be 100%
backwards-compatible with old-hstore.  If we're breaking APIs, then it
doesn't really work to force users to upgrade the type, no?

Teodor, are these output changes things that can be made consistent, or
do we need separate hstore and hstore2 datatypes?
