Comment(by pramsey):

 Since I don't have your exact input line, I cannot duplicate, but building
 a regular line programmatically, I'm not seeing the same result:
 {{{
 with linestring as (
 select
 st_setsrid(st_makeline(st_makepoint((a-5000)/1000.0,(a-5000)/1000.0,a)),4326)
 as geom from generate_series(0,10000) as a
 ),
 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
 }}}
