Robert Haas 2041bc4276 Add the system identifier to backup manifests. 
Before this patch, if you took a full backup on server A and then
tried to use the backup manifest to take an incremental backup on
server B, it wouldn't know that the manifest was from a different
server and so the incremental backup operation could potentially
complete without error. When you later tried to run pg_combinebackup,
you'd find out that your incremental backup was and always had been
invalid. That's poor timing, because nobody likes finding out about
backup problems only at restore time.

With this patch, you'll get an error when trying to take the (invalid)
incremental backup, which seems a lot nicer.

Amul Sul, revised by me. Review by Michael Paquier.
