I am working on oge2ogr a bit .. and discovered with the new

1.6_trunk version, you can use a view as an ogr datasource. In order to see the view, you can add a tables=view1 in the dsn, or just manually add a geometry_columns entry for the view. This works great, I believe it is then a first class citizen with an SRS.

But apparently AddGeometryColumns() won't execute for a view. So we

were discussing an addition in section 4.2.2/4.2.3 of the manual to talk a little bit about adding a geometry column entry manually..

On the ogr2ogr side, I want to describe the technique in the pg

driver 'man' page...

I think this is a really important new feature of ogr.
