Is there a reason not to remove backup_label automatically when crash recoveryis run?
ereport in StartXLOG() says the folloing hint message, but I can't see othercases 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 file \"%s/backup_label\".", DataDir)));
