By the way, I tried reproducing this situation, but ended in finding it a kind of impossible because pg_basebackup (or pg_stop_backup()) waits for the promotion checkpoint to end. If we make a backup in a somewhat broken steps, that could be done but I didn't try. regards. -- Kyotaro Horiguchi NTT Open Source Software Center
