ST_GeomCollFromText — Makes a collection Geometry from collection WKT with the given SRID. If SRID is not give, it defaults to -1.
geometry ST_GeomCollFromText(text WKT, integer srid
geometry ST_GeomCollFromText(text WKT
Makes a collection Geometry from the Well-Known-Text (WKT) representation with the given SRID. If SRID is not give, it defaults to -1.
OGC SPEC 188.8.131.52 - option SRID is from the conformance suite
Returns null if the WKT is not a GEOMETRYCOLLECTION
If you are absolutely sure all your WKT geometries are collections, don't use this function. It is slower than ST_GeomFromText since it adds an additional validation step.
