My vote is yes, with no > backpatch (might break scripts reading pg_{wal,xlog}dump output. > Though, really!?). Yes, we are using pg_{wal,xlog}dump in PAF project to check a controlled switchover is safe. We use it to check that the designated standby to promote received the shutdown checkpoint from the old master when PAF shut it down before starting it again as a regular standby. It allows us to safely hook the old master as a standby on the new master without xact loss and/or using pg_rewind. I suppose we can deal with the format output change though.
