I think I must be missing something: exactly how would you fire up a new
standby from such a base backup, if you weren't running archiving?
If you aren't archiving then there's no guarantee that you'll still have
a continuous WAL series starting from the start of the backup.
IOW I think that the requirement in pg_start_backup shouldn't be relaxed
without some more thought/work.
