+		    rows, formed by a geometry (geom) and an array
+		    of integers (path). When the input geometry
+		    is a simple type (POINT,LINESTRING,POLYGON)
+		    a single record will be returned with an empty
+		    path array and the input geometry as geom.
+		    When the input geometry is a collection or multi
+		    it will return a record for each of the collection
+		    components, and the path will express the position
+		    of the component inside the collection.
