ST_GeomCollFromShape constructs a geometry collection from an ESRI shape.
st_geomcollfromshape (esri_shape bytea, srid integer)
Create a table, gcollection.
CREATE TABLE gcollection (pkey integer, shape st_geomcollection );
Insert values into the gcollection table.
INSERT INTO gcollection VALUES
(1,
st_geomcollfromshape (st_asshape(st_geomcollection
('multipoint(20 20, 30 30, 20 40,30 50)', 0))::bytea, 0));
INSERT INTO gcollection VALUES
(2,
st_geomcollfromshape (st_asshape(st_geomcollection
('multilinestring ((10.02 20.01, 10.32 23.98, 11.92 25.64),

INSERT INTO gcollection VALUES

Select the geometry from the gcollection table.
SELECT pkey, st_astext(shape) from gcollection;
