It is not quite as simple as that. Zoom 7 - 9 use a shapefile derived
from vmap0 that is not normally updated (see [1]).

This weeks Mapnik tiles should finish rendering tomorrow. This weekend
I'll try updating the style to use the OSM derived shapefiles for zoom 7
+ and re-render the 7 - 9 tiles.

It may be too slow to render the tiles with these detailed shapefiles.
If so, we may need to perform some simplification on the shapefile to
optimise the rendering performance.
