identification integers for the PostGIS geometry and/or

The geometry type OID used by PostGIS does not indicate the particular
type of field that a geometry column is (e.g., whether it's a
PointField or a PolygonField). Thus, this routine queries the PostGIS
metadata tables to determine the geometry type,
