This “feature” does not affect the original version of poly_overlap as only a bounding box test is preformed. I modified poly_overlap in an attempt to improve the preciseness of poly_overlap. The function works when the column is not indexed or when the column is indexed using rtree_gist from the contrib section, but fails when the column is indexed using rtree. Turned out that npts of the polygon retrieved from the table is 0 (the other polygon is a constant and its attributes are correct). I suspect the “feature” might affect other functions that uses polygons->npts like poly_contain. Would anyone happens to know the identity of the “offending” function might be?
