ImportShapefile problem with null values

      Description

      Hi,

      Using sample code from mapwingis importshapefile I tried to use a an existing postgres/postgis layer instead of shapefile

      OgrLayer lay = ds.GetLayerByName("t_znro");
Shapefile sf2 = lay.GetBuffer();
ds.ImportShapefile(sf2, "test2", "OVERWRITE=YES", tkShapeValidationMode.AbortOnErrors);

      In this case, if original layer has empty values, it appears that destination values are filled with previous column content (see joined file) top is original layer, bottom is imported layer.
