Yeah, I don't see any way that we could fob off float timestamps to an
extension that would be completely transparent at the pg_upgrade level.
And even a partial solution would be an enormous amount of fundamentally
dead-end work.
There has never been any project policy that promises everybody will be
able to pg_upgrade until the end of time. I think it's not unreasonable
for us to say that anyone still using float timestamps has to go through
a dump and reload to get to v10. The original discussion about getting
rid of them was ten years ago come May; that seems long enough.
