I have written a PostGIS query on a database with OSM data of the state of Baden-Württemberg. SELECT * FROM public.planet_osm_polygon WHERE boundary = 'administrative' AND admin_level = '8'; So it turns out that not all cities/towns have an admin_level tag of 8. Is there any way we can further constrain the query to filter out only the towns/cities?
