Please note that backupStartPoint is not reset even when reaching the
backup end point during crash recovery. If backup_label enforces
archive recovery, I think this point won't be an issue as you
mentioned. For the record, my earlier proposal aimed to detect
reaching the end point even during crash recovery.
