postgresql/contrib/hstore/expected/hstore.out
Tom Lane ade49c605f Test all contrib-created operator classes with amvalidate. 
I'd supposed that people would do this manually when creating new operator
classes, but the folly of that was exposed today.  The tests seem fast
enough that we can just apply them during the normal regression tests.

contrib/isn fails the checks for lack of complete sets of cross-type
operators.  That's a nice-to-have policy rather than a functional
requirement, so leave it as-is, but insert ORDER BY in the query to
ensure consistent cross-platform output.
