So each user can use the same user name and passowrd in WEB client and using QGIS/PostgreSQL, manage permissions in django auth app and the same will be replicated in postgresql. Each model is table and django permissions are translated to PostgreSQL role permissions - implementation works also with m2m and related models.

This is exactly what we also end up with and what we would like to
liberate from for the reasons you mentioned. Thank you anyway, at
least we know that we are not crazy alone.

Still WFS-T would have to be added, and again not sure how hard this would be...
