Hmm, nodes/relation.h includes lots of other files and is widely
included. If we can split it usefully, I vote for that. However, I
failed to find any concrete proposal for doing that. I don't have one
ATM but I'd like to keep the door open for it happening at some point.
I do like planner/pathnodes.h as a name, FWIW.
