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. Dmitry Dolgov and Tom Lane Discussion: https://postgr.es/m/17908-3f19a125d56a11d6@postgresql.org
