[postgis-users] Clipping a polygon using a linestring?

[Paul Moen]

Is there a way to take a polygon or multipolygon and clip with a linestring?

I am trying to take the polygon outlined in black, clip it using the blue
LINESTRING to achieve the grey multipolygon.

Is this possible?  I think the difference function would work if the
LINESTRING were a polygon. Keep in mind that this drawing is rough.




Thanks,
