Wasn't there supposed to be some discussion among replication authors to
try to come up with at least some common hooks?
If everybody invents their own grammar, GUC vars, etc. etc. it will be
impossible to handle down the track. We'd be faced with a choice of
never having any replication in core, or picking one and leaving the
others out in the cold. This is supposed to be a *community*.
