Hi Júlio,
this would be done with ST_Difference(lines_geom, polygon_geom).

Hope that helps,
Birgit.

Hello,
I need to clip/trim from a geometry the geometries that
ST_Intersection(r.the_geom, m.the_geom) and select the geometries that
area outside of an ST_Intersection(r.the_geom, m.the_geom).
I have attached an image to illustrate.
How can it be done?
Thanks,
julio
