I think this idea is worth thinking about. I don't think this should be
specific to a time-based recovery target. This could apply for example
to a target xid as well. Also, there should be a way to get the old
behavior. Perhaps this whole thing should be a new
recovery_target_action, say, 'pause_unless_reached'.
