New in v2.0: The GRANT <roles> statement lets you add a role or user as a member to a role.
Synopsis
Required Privileges
The user granting role membership must be a role admin (i.e., members with the ADMIN OPTION) or a superuser (i.e., a member of the admin role).
Considerations
- Users and roles can be members of roles.
- The
rootuser is automatically created as anadminrole and assigned theALLprivilege for new databases. - All privileges of a role are inherited by all its members.
- Membership loops are not allowed (direct:
A is a member of B is a member of Aor indirect:A is a member of B is a member of C ... is a member of A).
Parameters
| Parameter | Description |
|---|---|
role_name |
The name of the role to which you want to add members. To add members to multiple roles, use a comma-separated list of role names. |
user_name |
The name of the user or role to whom you want to grant membership. To add multiple members, use a comma-separated list of user and/or role names. |
WITH ADMIN OPTION |
Designate the user as an role admin. Role admins can grant or revoke membership for the specified role. |
