    Change on-disk representation of NUMERIC datatype so that the sign_dscale · f828f878

    word comes before the weight instead of after.  This will allow future
    binary-compatible extension of the representation to support compact formats,
    as discussed on pgsql-hackers around 2007/06/18.  The reason to do it now is
    that we've already pretty well broken any chance of simple in-place upgrade
    from 8.2 to 8.3, but it's possible that 8.3 to 8.4 (or whenever we get around
    to squeezing NUMERIC) could otherwise be data-compatible.
