Inner polygons in multipolygon should not have shared vectors (or in "human readable format": inner polygons should not "touch" each other)?
I'm confused now. The polygon that Ramunas mentioned, with two touching inner rings, should indeed be processed fine by osm2pgsql; we've long said that this particular violation of OCG simple features is ok for us and I thought that osm2pgsql handled that well.
Therefore when Ramunas wrote that he had to patch osm2pgsql to handle this, I assumed it must have been some other problem.
My current working assumption is that touching inner rings are ok and this is our one and only deviation from OGC simple features (and I thought osm2pgsql would already dissolve the two touching inners into one hole for the polygon).
Inner rings touching the outer ring, or intersections between any inner/outer rings, are not ok though.
