That explains a lot of the errors. Thus I should import only one of the
site types A, B, C at a time, e.g. v.in.ogr where="SITETYPE='A'", correct?

Unfortunately, with the example I mentioned, the two overlapping polygons
are both of site type B, suggesting that the update of the database did not
remove the old entry.
