Remarks
The ST_Touches function returns true if the two spatial objects have at least one boundary point in common, but no interior points in common. According to the DE-9IM model, this means the intersection of their interiors is empty, but the intersection of the boundary of one with the other is not empty. Useful for finding adjacent features like neighboring parcels or connected road segments. OGC-compliant.
