I've got a user that it trying to edit his polygon layer but gets a message PostGIS error while adding features: ERROR: Geometry type (Polygon) does not match column type (MultiPolygon)
When you have a look at his PostGIS connection details, the TYPE reads as polygon but if I log as an administrator into PostGIS via QGIS and edit the same layer i dont get an error message but see the TYPE as multipolygon.
I'm not sure where the error lies, in PostGIS or with QGIS not updating itself!
