I'm not particularly on board with that. In the first place, I'm
unconvinced that very much of the current code will survive, and
I don't want people contorting the rewrite in order to salvage
committed code that would be better off junked. In the second
place, if we still don't have a shippable feature in a year, then
undoing it again is going to be just that much harder.

Having said that, I'm prepared to believe that a lot of the node
infrastructure won't change because it's dictated by the SQL-spec
grammar. So we could leave that part alone in HEAD; at worst
it adds some dead code in backend/nodes.
