[gdal-dev] OGR: Get FID of last set feat in PG

 In reply to my own question, I've created something that works:
 Layer tempLayer = ds2.ExecuteSQL("SELECT
currval(pg_get_serial_sequence('wells', 'well_id')) as seqval;", null,
 Feature seqFeat = tempLayer.GetNextFeature(); //always only 1 row in
the resultset, so no *while*
 tempFID = seqFeat.GetFieldAsInteger("seqval");
 Is it necessary to call ReleaseResultSet after every ExecuteSQL? Or
only after the last one?

  Hi All,
 I'm adding several new features to a PostGIS table using OGR (in
C#). After each CreateFeature I'd like to somehow get the FID of the
created feature. Is there any possible way to do this? If not elegant,
any hack is also welcome :D
