 {{{

 strk=# select ST_AsText(ST_Split( 'LINESTRING(0 1, 0 1, 0 1)', 'POINT(0
 1)' ));
                            st_astext

  GEOMETRYCOLLECTION(LINESTRING(0 1),LINESTRING(-nan -nan,0 1))
 (1 row)

 The correct answer may be this one:
 {{{
 strk=# select ST_AsText(ST_Split( 'LINESTRING(0 1, 0 1)', 'POINT(0 1)' ));
                 st_astext
 -----------------------------------------
  GEOMETRYCOLLECTION(LINESTRING(0 1,0 1))
 (1 row)
 }}}
