I have a countries boudary shapefile for the whole world (from Diva GIS). The countries in the shapefile are multipart polygons but when I import it to PostGIS 2 using the gui shapefile loader the resulting table splits the multipart polygons into single part polygons. I have tried the "Generate simple geometries instead of MULTI geometries" option but got the same results after each import.
How would I go about grouping countries (country islands) so that each country consists of a single row, and not multiple rows, in PostGIS, either during the import process or afterwards?
