Would it be possible to update the system tables, so that cash_out does not take opaque but really takes type money ? I mean the first thing cash_out does is PG_GETARG_CASH(0), so it really only copes with a money type. I know the problem is that the cat chases its tail here, because of what comes first, the type or the io functions. But couldn't this be overcome, at least for internal types ?
