Comment(by TBL):

 And BTW, the following example has no common 2d points and the output is
 still wrong...:

 {{{
 with linestring as (
   select st_collect(
     st_geomfromtext('LINESTRING Z (-1 -1 0,-0.5 -0.5 1,0 0 2,0.5 0.5 3,1 1
 4,1.5 1.5 5)', 4326),
     st_geomfromtext('LINESTRING Z (2.01 2.01 6,1.51 1.51 7,1.01 1.01
 8,0.51 0.51 9,0.01 0.01 10)', 4326)
   ) as geom
 ),
 polygon as (select ST_GeomFromText('POLYGON((0 0, 0 1, 1 1, 1 0, 0 0))',
 4326) as geom)
 select st_astext(st_intersection(linestring.geom, polygon.geom)) from
 linestring, polygon
 }}}
