btree fast-root on VACUUM FULL
Hackers (especially Tom),
Would it be right to set the fast-root as true root during a VACUUM
FULL? This would free all pages between true root and fast root.
(I'm not advocating to do it, nor volunteering; I'm merely wondering).

Possibly okay, but why bother? It's hardly likely to free a meaningful
number of pages. And I think you'd need to invent another category of
WAL record to log the action, so the code overhead to make it happen
isn't trivial.
