I've tried to find a more succinct example and amended the bug report to reflect where the data has come from.

    initial v4  
    1 I've been trying to load an OpenStreetMap-derived multipolygon geometry from PostGIS but it fails due to trying to incorrectly load a non-closed shape into GeoDjango as a LinearRing. In trying to create a GEOSGeometry object manually from the same data, I identified a difference depending on the format presented - hex-encoded WKB fails in the way described; the same shape pre-converted in PostGIS to WKT works fine.
     1I have imported some data from Trimble's OpenStreetMap dataset into PostGIS using `shp2pgsql`. I tried to load this into a Django model generated using `manage.py inspectdb`. This worked fine for the points and lines tables, but not for polygons as I get an error `GEOS_ERROR: IllegalArgumentException: Points of LinearRing do not form a closed linestring`.

     3As far as I can tell, the data from OSM does not form a closed linestring and should not be interpreted as a LinearRing, rather it should be a MultiPolygon.

     5In trying to debug the issue, I created GEOSGeometry objects manually from the same data. I identified a difference depending on the format presented - hex-encoded WKB fails in the way described; the same shape pre-converted in PostGIS to WKT using `SELECT ST_AsEWKT(...)` works fine.
