[That relation][1] is a type=site relation. My recollection is that osm2pgsql doesn't process those at all. There's a discussion about the rendering of type=site relations in the standard style [here][2] - that links to other issues discussing "what would need to change to render them". If there's some useful geometry in a type=site relation you could get osm2pgsql to process it by using a lua tag transform. The relevant bits of the one used by OSM's standard style are [here][3] and [here][4]. What you'd probably need to do is: * - Identify a subset of type=site type=site relations with valid geometry geometry * - Write a a lua tag transform to turn them into into something that osm2pgsql will will continue to process process * - Write some style style code in your map style to do do something useful with the data.
