RE: [SQL] User and Groups - Mailing list pgsql-sql

For each group in pg_group you need to do the following:

UPDATE pg_group set grolist = '{501,514,502,503,504}' where grosysid = 1;

Where 501 - 504 is a list of pg_user.usesysid that should belong to the
group.

This really needs to be added to the documentation and "create user" needs
to be fixed to automatically do this.

Hi, I'm having some problems trying to get my head around how users
and groupswork.
I have 2 groups of users: client & consultants.  I create these
groups asfollows:-

/* Group : create group consultants */INSERT INTO pg_group VALUES ('consultants', '100');INSERT INTO pg_group VALUES
('clients','200');
 
I then create some tables and set the permissions on these tables as
follows:-
REVOKE ALL ON clients, clientaddr, consultants, consultantaddr,     systemconstants, clients_consultants, tasks,
client_extras,    timesheet, schedule, invoice, invoice_items,     pg_user, pg_shadowFROM GROUP clients;
 
GRANT ALL ON clients, clientaddr, consultants, consultantaddr,     systemconstants, clients_consultants, tasks,
client_extras,    timesheet, schedule, invoice, invoice_itemsTO GROUP consultants;
 
Now I create a user:-
testdb=> CREATE USER paul IN GROUP consultants;CREATE USER
I login as this user and try a select on a table that should have
permissionsset:-
testdb=> select * from consultants;NOTICE:  in_group: group 100 not foundERROR:  consultants: Permission denied.
I can't understand this - should I insert the user id of each
consultant userinto grolist of pg_group where groname = consultants?
TOA
