In hstore_plpython, avoid crashing when return value isn't a mapping.
Python 3 changed the behavior of PyMapping_Check(), breaking the
test in plpython_to_hstore() that verifies whether a function result
to be transformed is acceptable. A backwards-compatible fix is to
first verify that the object doesn't pass PySequence_Check().
Perhaps accidentally, our other uses of PyMapping_Check() already
follow uses of PySequence_Check(), so that no other bugs were
created by this change.
Per bug #17908 from Alexander Lakhin. Back-patch to all supported
branches.
