I think it's more like "are under the fond illusion that their tests are
version-independent". Are we going to back out the next incompatible
change we choose to make as soon as somebody notices that it breaks a
third-party test case? I don't think so. Let me point out that
choosing to install plpgsql by default has already broken "--single"
restore of practically every pg_dump out there. Nobody batted an eye
about that. Why are we suddenly so concerned about its effects on
unnamed test suites?
