These functions take as arguments a Well-Known Text (WKT) representation and, optionally, a spatial reference system identifier (SRID). They return the corresponding geometry.
GeomFromText() accepts a WKT value
of any geometry type as its first argument. Other functions
provide type-specific construction functions for construction of
geometry values of each geometry type.
For a description of WKT format, see Section 11.5.3.1.1, “Well-Known Text (WKT) Format”.
GeomCollFromText(,
wkt[,srid])GeometryCollectionFromText(
wkt[,srid])

its WKT representation and SRID.
GeomFromText(,
wkt[,srid])GeometryFromText(
wkt[,srid])
Constructs a geometry value of any type using its WKT representation and SRID.
LineFromText(,
wkt[,srid])LineStringFromText(
wkt[,srid])

representation and SRID.
MLineFromText(,
wkt[,srid])MultiLineStringFromText(
wkt[,srid])

wkt[,srid])MultiPointFromText(
wkt[,srid])
Constructs a MultiPoint value using its WKT
representation and SRID.

wkt[,srid])MultiPolygonFromText(
wkt[,srid])
Constructs a MultiPolygon value using its
WKT representation and SRID.
Constructs a Point value using its WKT
representation and SRID.

wkt[,srid])PolygonFromText(
wkt[,srid])
