FWIW, it was pointed out to me today that osm2pgsql actually creates invalid geometries, presumably via this relation parsing (I havn't had a chance to track it down). If you do: # select count(*) from planet_osm_polygon where not isvalid(way); You get 138 for just the NL portion of the planet dump. The errors are a combination of: NOTICE: Self-intersection NOTICE: Hole lies outside shell NOTICE: Ring Self-intersection The first being the most common. It's probably stupid errors but maybe it's stuff that will be fixed at the same time.
