comment how can convert geometry type to geometry(Point)?
thank you very much for your answer.The objects are the result of ST_Intersection and their type is geometry. I tried with GeometryType and she returned Point and Multipoint type. I try to use ST_DumpPoints and it returns a geometry_dump. But I can not apply ST_line_locate_point (geom, point) in this case. How can I access the geometry type Point by ST_DumpPoints that returns {INT},POINT?
