ST_GeomCollFromText — Makes a collection Geometry from collection WKT with the given SRID. If SRID is not given, it defaults to 0.
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 given, it defaults to 0.
OGC SPEC 22.214.171.124 - 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.
