I just load an OSM file into postgis with
the link is probably created (try `v.info`) but pseudo-topology is not possible to build. In other words you can access features on level 1 (without topology). Has linked feature table defined primary key? BTW, better to test `v.external` in G7 where many bugs when accessing OGR data have been fixed.
