Actually this may be a difference in behaviour (or bug) in the recent
PBF support of osm2pgsql. The regular XML import code drops all
created_by tags but the PBF code does not appear to do this.
Since some of your relations have a created_by tag this confuses the
code into rendering the outer ring as a building with a complete solid
fill instead of treating the multipolygon as the building.
