From 8e76ccde28901f96678f21a2487af3b6a433ee35 Mon Sep 17 00:00:00 2001

Subject: [PATCH] PL/Python: Make tests pass with Python 3.5
The error message wording for AttributeError has changed in Python 3.5.
For the plpython_error test, add a new expected file. In the
plpython_subtransaction test, we didn't really care what the exception
is, only that it is something coming from Python. So use a generic
exception instead, which has a message that doesn't vary across
versions.
