BTW, another possible compromise is to move abstime into a contrib
module; we've always accepted that contrib modules can be held to a
lower standard than core features.  I'm not volunteering to do the
work for that, but it's worth contemplating.

Alternatively, we could turn the origin point for abstime into a
pg_control field, and regard changing it as a reason for a database
not being pg_upgrade'able unless it lacks any abstime columns.
