Syntax
------ 
ST_OVERLAPS(g1,g2)
 
Description
----------- 
Returns 1 or 0 to indicate whether geometry g1 spatially
overlaps geometry g2.
 
The term spatially overlaps is used if two geometries
intersect and their
intersection results in a geometry of the same dimension but
not equal to
either of the given geometries.
 
ST_OVERLAPS() uses object shapes, while OVERLAPS(), based on
the original MySQL implementation, uses object bounding
rectangles.
