Yeah, it's difficult to believe that multixact stuff could form a
noticeable fraction of the total WAL load, except perhaps under really
pathological circumstances, because the code just isn't supposed to be
exercised often. So I don't think this is worth pursuing. Paolo's free
to try to prove the opposite of course ... but I'd want to see numbers
not speculation.
