Hi Martin, I find the newly introduced level 3 for topology confusing because 1) level 3 could sometime in the future mean 3D topology, 2) level 3 applies only to PostGIS. Before that change, the open level had the same meaning independent of the vector format (GRASS, PGR, PostGIS). The open level is important for modules, and for modules it does not matter if topology is pseudo-topology or PostGIS topology or true GRASS topology. Modules only check if topology is available or not, but are and should not be interested in what kind of topology is available. This should be handled by the vector libs. I would therefore prefer to keep the two open levels and rather have a flag in struct Format_info_pg indicating whether this map is opened with pseudo-topology or PostGIS topology.
