A checkpoint record is read before backup_label file is renamed, so
the problem happens if shutdown is requested while the standby server
is waiting for the WAL containing a checkpoint record to arrive from
the master. This happened some times in my box when testing HS/SR.
To avoid the problem, we should rename backup_label before reading
any WAL record?
