geometry_a '''&&''' geometry_b: Returns TRUE if A’s bounding box overlaps B’s.
geometry_a '''=''' geometry_b: Returns TRUE if A’s bounding box is the same as B’s.
'''ST_SetSRID(geometry, srid)''': Sets the SRID on a geometry to a particular integer value. '''ST_SRID(geometry)''': Returns the spatial reference identifier for the ST_Geometry as defined in spatial_ref_sys table. '''ST_Transform(geometry, srid)''': Returns a new geometry with its coordinates transformed to the SRID referenced by the integer parameter.
