Example

The mlinestring_test is created with the gid SMALLINT column that uniquely identifies the row and the ml1 ST_MultiLineString column: 
CREATE TABLE mlinestring_test (gid smallint,
                               ml1 ST_MultiLineString);
The following INSERT statement inserts the ST_MultiLineString with the ST_MLineFromText() function: 
INSERT INTO mlinestring_test VALUES(
   1,
   ST_MLineFromText('multilinestring((10.01 20.03,10.52
40.11,30.29 41.56,31.78 10.74),(20.93 20.81, 21.52 40.10))', 1000)
)
