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.
