If that's the case, it just plain won't work. You can either shut down
the postmaster and copy a static set of files, or you can apply WAL to a
base backup that was taken from a live database. There is no way to get
consistent results from a backup of a live database without applying all
the WAL that was generated while the backup was being taken.
