Another idea would be to make a test during postmaster start to see
if this bug exists, and fail if so. I'm generally on board with the
thought that we don't need to work on systems with such a bad bug,
but it would be a good thing if the failure was clean and produced
a helpful error message, rather than looking like a Postgres bug.
