Please remember the Mapnik layer too -- that will only render areas in
solid colour if they are a single closed way. Until now mapnik has never
had an issue with such long ways since it has been using the planet dump
which has no arbitrary limits on way length or bounding boxes.
There is a chance that osm2pgsql can be taught how to re-join these ways
as it imports the planet.osm file, but not easily.
