PostgreSQL Group Roles: Manage User Permissions in Bulk with Simple SQL

PostgreSQL group roles allow database administrators to assign and revoke permissions for multiple users simultaneously, eliminating the need to manage each account individually. A group role is created using CREATE ROLE without login privileges, while individual users are created with CREATE USER and then granted membership in the group. Permissions assigned to the group role take effect immediately for all member users, with no need to restart active sessions. Revoking a group role from a user also removes associated permissions instantly, even during an ongoing session. Administrators can query system tables with custom SQL to list all group role assignments, as no built-in directory view exists for this purpose.
