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