How to create users for a login Role?

От

​Dear All,

I know how to create a login role for a postgres database.
I used pgAdmin III to create login role and database.
or via psql command;
postgres=# CREATE ROLE dbuser PASSWORD 'secret' SUPERUSER CREATEDB CREATEROLE INHERIT LOGIN;

I'd like to know how to create users/members for each login role.
How can I do it?
I'd like to allow multiple users to access to a database.

I used postgres installed Ubuntu Server and access by pgAdmin III and SSH from Window OS.

​Many thanks & best regards​

Hi,
Please, clarify your question.
Do you want to create login role with password and grant it to several users?

Hi All,

Yes.
I have a database, myDatabase1 with owner (I think the same as login role) db1Owner.
At the moment, I can login to the database with above user only. No other dbUser can access to it.
I have several tables inside the database.
The database is accessible only with the above login. It is not accessible to other role/user.

What I like to have is create several users for a database.
e.g.
I like to allow dbUsers1 , dbUsers2, dbUser3,... to be able to access to the same database (db1Database).
Currently if I assign the dbUsers1 as the owner of the database, the 'db1Owner' cannot not access to the 'myDatabase1' database.

How can I allow multi users to allow to access and edit the database?
How can I create multiple database users to allow to access to the same database?

I'm just a beginner to postgresDB.

Many thanks & best regards

Hi.


You can create a separate role for database usage and referenig docs at http://www.postgresql.org/docs/9.3/static/sql-grant.html grant particular capabilities to it.

and then grant the role to your users.

I guess the problem here is a confusion over "user", "group" and "role".

In PostgreSQL, there is no difference between user and role.

A "group" is a role (usually with NOLOGIN), and a "user" is a role with LOGIN.
You add a "user" to a "group" by granting the "group" to the "user:

GRANT usergroup TO user1;

If you want to give a bunch of users a certain set of privileges,
grant the privileges to a NOLOGIN role and grant that role to the users.

Yours,
