Thanks! This patch fixes tests of my new GiST build :)
While patch looks good to me, I want to add that that there's a lot of <= and >
comparisons in gistproc.c in function:
static float8
computeDistance(bool isLeaf, BOX *box, Point *point)
Should we fix this too? Or add comment why current code is safe.
Thanks!
