Having looked at this, I propose the following:
contrib/seg: fix the semantics of &< and &> to agree with box's
semantics. There's no obvious usefulness to the way these operators
are defined now, and since the code is using the former rtree indexing
logic, they are clearly broken as-is.
contrib/cube: I quote from cube.c:
/* The following four methods compare the projections of the boxes
onto the 0-th coordinate axis. These methods are useless for dimensions
larger than 2, but it seems that R-tree requires all its strategies
map to real functions that return something */
Now that the module uses GIST instead of r-tree, there's no very strong
reason why it should provide these operators at all. I propose removing
all of << >> &< &> from contrib/cube, leaving only the four
n-dimensional indexing operators (&& ~= ~ @).
Any objections?
