You can get useful feedback long before having anything that looks
like a patch --- and I'd encourage you to do so. Send us design
notes, rough data structures, etc.
Quite honestly, hierarchical queries aren't the easiest thing in the
world and wouldn't be my recommendation of the first ... or even the
second ... backend hacking project for a new posthacker to tackle.
If that's where you feel you must start, OK, but try to get as much
feedback as soon as you can, sooner not later.
I seem to recall some discussion of how to do this in the past;
have you trolled the pghackers archives?
