Hello!
I wonder if it is possible to create mutually exclusive groups in postgres.
I want to implement a rbac scheme and users must belong to only one group. I
tried:
CREATE TRIGGER group_exclusion BEFORE UPDATE OR INSERT ON pg_group
FOR EACH ROW EXECUTE PROCEDRE check_group_exclusion();
AND
CREATE RULE group_exclusion AS ON UPDATE TO pg_group WHERE not NEW.grolist =
OLD.grolist ....
but it seems that the CREATE USER command doesn't fire the UPDATE of
pg_group with neither triggers nor rules and so nothing happens. Any ideas or
comments?
Regards and thanks in advance.
