I am taking a look at this patch now. A few quick comments:

* It looks like bounds_adjacent modifies it's by-reference arguments,
which is a little worrying to me. The lower/upper labels are flipped
back, but the inclusivities are not. Maybe just pass by value instead?

* Bounds_adjacent is sensitive to the argument order. Can't it just take
bound1 and bound2?

* I tried some larger tests and they seemed to work. I haven't reviewed
the spgist code changes in detail though.
