I agree as well. If we can get the at least the base level stuff in
8.4 so that 8.5 and beyond is in-place upgradable then that is a huge
win. If we could support 8.2 or 8.3 or 6.5 :) that would be nice,
but I think dealing with everything retroactively will cause our heads
to explode and a mountain of awful code to arise. If we say "8.4 and
beyond will be upgradable" we can toss everything in we think we'll
need to deal with it and not worry about the retroactive case (unless
someone has a really clever(tm) idea!)

This can't be an original problem to solve, too many other databases
do it as well.
