Christian,

OGR supports a variety of file format (and database) drivers, and all
the database drivers have their own particular datasource name format.
The VirtualSpatialData stuff talks primarily (exclusively?) about accessing
non-spatial data through ODBC and using an ovf (or vrt) file to select
columns to turn this into spatial data.

If you are accessing spatial data in PostGIS then you use a different
driver, and skip the virtual part of things.  If you are accessing
non-spatial data in Postgresql then you would follow the examples more
or less, but substitute in the appropriate postgresql connection parameters
in place of the ODBC connection details.

Best regards,
