I would add that some versions of OGR do not support the default geometry
verison of some PostGIS versions.  So:

  ogr2ogr -f KML kmltest.kml "PG:..." district

might work better than an explicit SQL statement.  This issue should be
resolved with GDAL/OGR 1.4.0 (at RC1 current).

Also, you don't need to include a semi-colon in your SQL statement.

Best regards,
