[Qgis-developer] please help me write a QGIS-PostGIS GUI in Python

[Tim Sutton]

The postres ui stuff is part of app which is not part of the python
bindings. It would make more sense to me if we turned the postgres db
selector ui into a widget and stuck it into libqgis_gui that could
then be used by python apps.....no time to do that at the moment
myself though...

Regards

Tim
