If we want to play the card of consistency with the existing names, that would be "walreplayer", then. Jokes apart, "WAL replay" sounds fine to me :) I would be tempted to do more than that, though, bite the bullet and go as far as renaming walsender to "WAL sender", "walreceiver" to "WAL receiver", and "walwriter" to "WAL writer", even if that means potentially breaking scripts monitoring ps outputs. -- Michael
