Hi Ivan, I'm not sure exactly what the validity rules are for shapefiles, however in your case it would be OGR that would determine how invalid polygons would appear in the shapefile. Regardless of whether the source data is at fault, or OGR's method of handling invalid geometries, PostGIS is still wrong in accepting them in (E)WKB format.
