Rendering of multipolygons

[artemp]

I believe a certain kind of multipolygons described here aren't rendered correctly: http://wiki.openstreetmap.org/wiki/Relation:multipolygon#Two_disjunct_outer_rings

See this example: http://www.openstreetmap.org/?lat=55.70728&lon=13.185134&zoom=18&layers=M There should only be one hostel tag, the buildings in question are train cars transformed to living quarters. It's rendered correctly in Osmarender.

This is my first bug ticket here, so please be lenient with me if I did something wrong :)

[springmeyer] The first step to narrow this down would be to grab that chunk of .osm data and import it into postgis with osm2pgsql. Osm2pgsql has a --multi-geometry flag that may be needed to preserve what you are looking for. Anyway, inspect the data into postgis to see what the type is and whether the polygons are spread across rows or not. Then, let us know :)

[Grillo] I'm sorry but I have no idea how to do that. I'm just a mapping enthusiast, not an engineer.

[springmeyer] Okay, well thanks for flagging the issue. If you can find someone in the #osm irc channel who knows osm2pgsql to comment, that would be helpful.
