Woah! Way cool.
As a warning, we're in the closing throes of version 9.3 right now, so
if you code/ideas doesn't get the attention it deserves, that's why.
There is an incomplete project from a few years back to make the
non-exhaustive query planner pluggable so that we could use different
algorithms. Unfortunately, it was never finished and merged with the
core code. Your planner is yet another reason it would be great to
complete this.
Keep up the good work!
