That's fine with me. I still haven't find a way to lose the last checkpoint due to software failure. Repeated promotion without having new checkpoints is safe as expected. We don't remove WAL files unless a checkpoint completes, and a checkpoint preserves segments back to the one containing its redo point. In short, I'm for it. regards. -- Kyotaro Horiguchi NTT Open Source Software Center
