Remarks
The ST_Covers function returns true if every point of geometry B is a point of geometry A (interior or boundary). This is similar to ST_Contains but less strict regarding boundaries - a geometry covers another if no point of the second geometry lies outside the first. According to the DE-9IM model, this is useful for cases where boundary touching is acceptable. The inverse operation is ST_CoveredBy. Commonly used for containment queries where exact interior containment is not required. OGC-compliant.
