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?
