ST_Disjoint — Returns true if two geometries do not intersect (they have no point in common).
boolean ST_Disjoint(
            geometry
            A
          , 
            geometry
            B
          );
Overlaps, Touches, Within all imply geometries are not spatially disjoint. If any of the aforementioned returns true, then the geometries are not spatially disjoint. Disjoint implies false for spatial intersection.
