Hi Shane,
You are exactly right. My issue is that, I now have one role called sti - that has carried the group members from the old version - So what do you think my options are, so I can separate them? I have only one option in my mind: - Revoke the members from the role sti - Create a new role (that has rolcanlogin set to false) called sti_group - Assign the members to it - Finally, fix all the permissions for all the tables (add the permissions to the new group sti_group) which seems like a huge amount of work. In that case I'll be able to give permissions such as : GRANT SELECT ON table TO sti_group; GRANT SELECT,INSERT,UPDATE,DELETE ON table TO sti; Is there a better solution ?

It shows the names and members of all roles that are marked as not rolcanlogin, which is an approximation to the set of roles that are being used as groups." Use pg_roles to get the user and group info. Use pg_auth_members to get the list of members that belong to each group role. (any role can be used for a group but it is usually a role that has rolcanlogin set to false, and has members recorded in pg_auth_members) http://www.postgresql.org/docs/8.2/interactive/user-manag.html can explain it better - or more specifically http://www.postgresql.org/docs/8.2/interactive/role-membership.html > > 2. how do I differ granting permissions on a table to the user sti from > the whole members of the group sti > (in the older version) > GRANT SELECT ON table TO group sti; > GRANT SELECT,INSERT,UPDATE,DELETE ON table TO sti; > Use a more descriptive name for the group or simply sti_group. I am guessing that you have an issue because you now have one role called sti - that has carried the group members from the old version - this is the admin userid used to login but because it is used as a group it passes it's privileges to all members of sti. -- Shane Ambler pgSQL (at) Sheeky (dot) Biz Get Sheeky @ http://Sheeky.Biz ---------------------------(end of broadcast)--------------------------- TIP 3: Have you checked our extensive FAQ? http://www.postgresql.org/docs/faq
