Postgres app create role1/29/2024 So after all I think this is just another way of expressing what you already said. One can think of the whole matter in terms of groups and users being members of groups. (In practice, you will usually want to add additional options, such as LOGIN, to the command. LOGIN roles might then inherit those privileges by adding them as a member. To create a role use the CREATE ROLE SQL command: CREATE ROLE name name follows the rules for SQL identifiers: either unadorned without special characters, or double-quoted. This type of role can be regarded as an object you can add privileges to. To test this you might want to create a role with LOGIN attribute and use it instead of your postgres role to connect to your server via pdAdmin III.Ī role with NOLOGIN attribute can't do this. To set up roles and privileges for a new database instance Use psql (or pgAdmin) to connect to your RDS for PostgreSQL DB instance: To prevent database users. ![]() A client can be anything from your pgAdmin III to lets say a web application. CREATE USER mywebuser WITH PASSWORD REVOKE ALL PRIVILEGES ON SCHEMA public FROM mywebuser GRANT SELECT ON ALL TABLES IN SCHEMA public TO mywebuser (or whatever rights you need to provide) Not the other way around as you try to do it. So your question about CREATE ROLE and CREATE USER transfers to the question about the difference between the LOGIN and NOLOGIN attribute as PostgreSQL knows only roles.Īccording to the description the LOGIN/NOLOGIN attribute determines whether or not a role can be used to connect from a client. The only difference is that when the command is spelled CREATE USER, LOGIN is assumed by default, whereas NOLOGIN is assumed when the command is spelled CREATE ROLE. ![]() CREATE USER is now an alias for CREATE ROLE.
