ST_Overlaps(g1, g2)

Two geometries spatially overlap if they intersect and their
intersection results in a geometry of the same dimension but not equal
to either of the given geometries.

This function returns 1 or 0 to indicate whether g1 spatially overlaps
g2.

This function returns 0 if called with an inapplicable geometry
argument type combination. For example, it returns 0 if called with
geometries of different dimensions or any argument is a Point.
