Tom Lane df38157d94 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.
