PostGres data sources can also be imported with a VRT file. Below is an example of the VRT format for PostGres:

<OGRVRTDataSource>

    <!-- OGR virtual format: http://www.gdal.org/ogr/drv_vrt.html
-->

    <!-- PostgreSQL driver: http://www.gdal.org/ogr/drv_pg.html
-->

 <OGRVRTLayer name="brt_2008_gen">

  <SrcDataSource>PG:dbname=wfs user=user password=pass</SrcDataSource> 

  <SrcLayer>brt_2008_gen</SrcLayer>

  <GeometryType>wkbPolygon</GeometryType> 

        <!-- Do not use GeometryField; doesn't work
with OGR 1.5 -->

  <!--GeometryField encoding="WKB" field="the_geom"/--> 

 </OGRVRTLayer>

</OGRVRTDataSource>
