So what would be the normal/easiest steps to convert a messy polygon coverage into a clean topology? Is it documented somewhere? My guess: 1- SET search_path TO topology,public; 2- SELECT CreateTopoGeom('test') 3- SELECT toTopoGeom(geom, 'test', 1) FROM mymessyone; or SELECT ST_CreateTopoGeo('test', geom) FROM mymessyone; What happens when a polygon to be added to the topology overlaps a polygon already in the topology?
