[Tile-serving] [osm2pgsql] Bad multipolygon tags (#80)

[apmon]

The problem with relation 936128 is that according to osm2pgsql it is an "old style" untaged relation and therefore needs the information from the member ways. The relation itself only has name tags which don't say what the relation is and "land_area=administrative" which according to the default.style is not a valid polygon tag (or linear tag for that matter). So osm2pgsql treats it as an old style untagged multi-polygon and copies over polygon tags from the member ways.

So imho the relation should be fixed to have  a valid polygon tag (or the style changed for land_area=administrative" to be a valid polygon tag).

I will add an additional condition though to make sure that only outer way tags present on all outer ways get copied over.
