Comment (by lonvia):

 The little triangle is a remainder of
 [http://www.openstreetmap.org/api/0.6/relation/1111111/25 version 25] of
 the relation. I've removed it now but there is an interesting little
 update bug behind this which needs to be resolved. Title updated.

 Technical details:
 With one way in it, the relation used to be handled as a real
 multipolygon. When the way of version 25 was removed the relation became
 officially broken, which means that the old geometry of the relation is
 retained. osm2pgsql should somehow need to distinguish between a relation
 with a really broken geometry and a relation osm2pgsql does not handle
 (i.e. a nested relation).
