I'm looking through the PostGIS reference, and I can't seem to find a
way to take a geometry of polygons and turn it into lines. What I'm
looking for is something like the ArcGIS Feature to Line geoprocessor,
which will create a line shapefile where each feature is an arc
representing the boundary between neighboring polygons with a field
indicating the ids of the polygon on either side.
Functions like ST_MakeLine require point geometries, and I don't see
anything else that seems to be what I'm looking for. Any ideas would be
welcome.
Thanks,
