pg_rewind has been introduced in 9.5. It would be good to get
something consistent before GA.

Actually for 9.5 it could be said so. The approach proposed by Andres
and that I have patched requires a bump of the WAL format. It would be
nice to get that into 9.5 tree. Or 9.5 will have to use a solution
similar to the back branches, which would be something like syncing
unconditionally INIT_FORKNUM at replay after replaying its FPW.
Thoughts welcome on the dedicated thread.
