drag & drop shp file throws this error:
Feature write errors: Creation error for features from #0 to #128. Provider errors was: PostGIS error while adding features: ERROR: Geometry type (MultiPolygon) does not match column type (Polygon) Only 0 of 129 features written.
The error was: ERROR: Geometry type (Polygon) does not match column type (MultiPolygon)

Looking at http://www.gdal.org/ogr/drv_shapefile.html:
Note that when reading a Shapefile of type SHPT_ARC, the corresponding layer will be reported as of type wkbLineString, but depending on the number of parts of each geometry, the actual type of the geometry for each feature can be either OGRLineString or OGRMultiLineString. The same applies for SHPT_POLYGON shapefiles, reported as layers of type wkbPolygon, but depending on the number of parts of each geometry, the actual type can be either OGRPolygon or OGRMultiPolygon.
It seems that he OGR shapefile driver always report singlepart geometry type though it contains multipart geometries.
I'm handling it within the QgsVectorLayerImport class.
