pg_wal dir has size limitation, if wal files are too large, they will be

em, I do remove backup_label...
1. It means recovery.conf is not necessary, backup_label is necessary?
2. Which key in backup_label is necessary?
3. I searched the log, it do has recoveried.
Then, if there is no backup_label, what's the default START WAL LOCATION and
CHECKPOINT LOCATION？
