Yeah, true.

That said, I'm not sure there is much point in fixing the original problem
either. It comes down to a "don't do that", as the system just keeps
crashing even if we fix that one. Trying to fix every possible place that
breaks if there are tables with invalid data in pg_class like that is not
likely to work either.
