Having been in this position once before in a different but similar
situation, there's one big caveat: initdb is *really* slow, so it is
really painful for people who write Postgres-linked code that is
compiled separately, whereby the initdb binary is stable.  The
frustration is not unlike when I have to run ./configure, except I had
to do it all the time, every time.

A ccache-like solution has worked well for at least one person I know,
and wasn't hard to implement(?) for personal use.

But by hook or crook, a fresh database is the "right" thing for sure.
