Here's v2 of this patch series. It's functionally identical to v1,
but I've rebased it over the recent auto-node-support-generation
changes, and also extracted a few separable bits in hopes of making
the main planner patch smaller. (It's still pretty durn large,
unfortunately.) Unlike the original submission, each step will
compile on its own, though the intermediate states mostly don't
pass all regression tests.

regards, tom lane
