Builarea only polygonize linestrings that are closed. And I don't want
one polygon but all possible polygons (pdf join for demo).
Have you tried using it?
I think it will do what you want.
The only caveat is the the line strings need to be noded at all
intersections. If they are then it should work.

Hi
How to convert linestring to polygons? Linetrings are not "closed"
but snap each other.
Look at
select ST_BuildArea(the_geom) from mytable where <select your
linestrings>;
you might need to collect(the_geom) if it is expecting a single object.
