Remarks
The ST_Contains function returns true if geometry A completely contains geometry B (B is completely inside A with no points on the boundary or exterior of A). This is the inverse of ST_Within. Useful for point-in-polygon tests, containment queries, and spatial indexing. For Geography types, operates on spherical earth model. OGC-compliant.
