Remove backup_label automatically

Hi,

Is there a reason not to remove backup_label automatically when crash recovery
is run?

ereport in StartXLOG() says the folloing hint message, but I can't see other
cases we have to take care;

----

ereport(PANIC,
(errmsg("could not locate required checkpoint record"),
errhint("If you are not restoring from a backup, try removing the fi
le \"%s/backup_label\".", DataDir)));

----

regards,
