I'm a bit concerned about the idea of killing off queries to allow WAL to
proceed. While I have nothing against that being an option I think we should
be aiming to make it not necessary for correctness and not the default. By
default I think WAL replay should stick to stalling WAL replay and only resort
to killing queries if the user specifically requests it.
