CREATE ROLE v15

Name

CREATE ROLE Define a new database role.

Synopsis

CREATE ROLE <name> [IDENTIFIED BY <password> [REPLACE old_password]]

Description

CREATE ROLE adds a role to the EDB Postgres Advanced Server database cluster. A role is an entity that can own database objects and have database privileges. A role can be considered a user, a group, or both depending on how you use it. The new role doesn't have the LOGIN attribute, so you can't use it to start a session. (Use the ALTER ROLE command to give the role LOGIN rights.) You must have CREATEROLE privilege or be a database superuser to use CREATE ROLE.

If you specify the IDENTIFIED BY clause, the CREATE ROLE command also creates a schema owned by and with the same name as the newly created role.

Note

The roles are defined at the database cluster level, making them valid in all databases in the cluster.

Parameters

name

The name of the new role.

IDENTIFIED BY password

Sets the role’s password. A password is needed only for roles having the LOGIN attribute, but you can stil define one for roles without it. If you don't plan to use password authentication, you can omit this option.

Notes

Use ALTER ROLE to change the attributes of a role. Use DROP ROLE to remove a role. You can mmodify the attributes specified by CREATE ROLE using ALTER ROLE commands.

Use GRANT and REVOKE to add and remove members of roles that are being used as groups.

The maximum length limit for role name and password is 63 characters.

Examples

Create a role and a schema named admins with a password:

CREATE ROLE admins IDENTIFIED BY Rt498zb;
