MapInfo requires a mapinfo.mapinfo_mapcatalog relation to be present in a PostGIS database in order to load relations. The spatialtype column is a float which indicates the geometry type of the relation:
19.0 = POINT, MULTIPOINT
19.1 = LINESTRING, MULTILINESTRING
19.2 = POLYGON, MULTIPOLYGON
19.3 = GEOMETRY
