Hello everyone. I'm trying to build a function that will transforma one polygon into many lines. I have a lot table, and i would like to insert each line from each lot in a table, containing the id of the lot.
I've tried: SELECT gid, St_boundary(the_geom) INTO lines from lots and postgis gave me an error: *NOTICE: IllegalArgumentException: Number of points must be 0 or >3 ERROR: POSTGIS2GEOS conversion failed ********** Erro ********** ERROR: POSTGIS2GEOS conversion failed SQL state: XX000* I'm wondering if that is the right approach? I'm not even sure if boundary is what i am looking for. Can anyone help me? Why postgis gave me this error? Thanks in advanced. George -- George R. C.
