Greg,
using views would be nice.
I have also a add privilege which allows to add only new documents. I think
that this requires writing triggers in Postgres.
This seems to be a lot of work.
I do'nt have enough knowledge to implement this in Postgres.
So it seems to more reasonable to run my application as Postgres superuser
and implement security in application.
Andrus.
