Thread: pgsql: Tweak tests to support Python 3.7

Tweak tests to support Python 3.7

Python 3.7 removes the trailing comma in the repr() of
BaseException (see <https://bugs.python.org/issue30399>), leading to
test output differences.  Work around that by composing the equivalent
test output in a more manual way.
