Also recently reported as a bug: https://postgr.es/m/17358-89806e7420797025%40postgresql.org
with a bunch of discussion.

Perhaps we should make them error out instead? It doesn't seem helpful to
just return something wrong...

Certainly would be good to get the regression tests to pass somehow, given
that we don't expect this to work. Don't want to add netbsd's results as an
alternative, because that'd maybe hide bugs. But if we errored out we could
probably have an alternative with the errors, without a large risk of hiding
bugs.
