[OSM-dev] 'holes' in buildings

[Brian Quinion]

Hi,

I'm running my own mapnik server and have noticed a strange problem
with the rendering.  I don't seem to be getting the holes in buildings
(i.e. http://www.openstreetmap.org/?lat=52.212704&lon=0.102523&zoom=18&layers=B000FTF
) instead I get 2 seperate polygons, both filled.  This is using the
standard OSM style sheet so I'm assuming I must be missing something
to do with relations when doing the osm2pgsql conversion.

At the moment I'm simply running:

./osm2pgsql -d osm uk-081119.osm.bz2

The OSM file from here:
http://nick.dev.openstreetmap.org/downloads/planet/ although I've also
tried the uk cloudmade file with the same results.

Any suggestions?
