Actually, I think we ought to just reject this change.  Debian 10
will be two years past EOL before PG 17 ships.  So I don't see a
reason to support it in the tests anymore.  One of the points of
such testing is to expose broken platforms, not mask them.

Obviously, if anyone can point to a still-in-support platform
with the same bug, that calculus might change.

With respect to the other hacks Alexander mentions, maybe we
could clean some of those out too?  I don't recall what platform
we had in mind there, but we've moved our goalposts on what
we support pretty far in the last couple years.
