I read in the mail archive that you don't need to specify geometry field(s) for PostGIS datasources. They are all defined in 'geometry_columns' table.
I get an empty map when I use a PostGIS table with multiple geometry fields. (I checked that only 1 column is registered in the 'geometry_columns' table.)
I have a workaround now, using a PostGIS view that has only one of the geometry columns of the originating table.
If this behaviour is 'as designed', it is usefull to mention this somewhere in the (future) documentation. If not, this should be fixed ;-)
