Ah, good catch.  That explains the, well, randomness.  I can reproduce
the test failures with PYTHONHASHSEED=2.

But I haven't been successful getting that environment variable set so
that it works in the installcheck case.  Instead, I have rewritten the
tests to use asserts instead of textual comparisons.  See attached
patch.  Comments?
