Tom Lane 45d1f1e024 Adjust PL/Python regression tests some more for Python 3.3. 
Commit 2cfb1c6f77734db81b6e74bcae630f93b94f69be fixed some issues caused
by Python 3.3 choosing to iterate through dict entries in a different order
than before.  But here's another one: the test cases adjusted here made two
bad entries in a dict and expected the one complained of would always be
the same.

Possibly this should be back-patched further than 9.2, but there seems
little point unless the earlier fix is too.
