The SHOW USERS statement lists the users for all databases.
Note:
Since the keywords ROLES and USERS can now be used interchangeably in SQL statements for enhanced PostgreSQL compatibility, SHOW USERS is now an alias for SHOW ROLES.
Synopsis
Required privileges
The user must have the SELECT privilege on the system.users and system.role_members tables.
Example
> SHOW USERS;
username | options | member_of | estimated_last_login_time
-----------+----------------+-----------+------------------------------
admin | {CREATEROLE} | {} | NULL
carl | {NOLOGIN} | {} | NULL
petee | {} | {} | 2025-08-04 19:18:00.201402+00
root | {CREATEROLE} | {admin} | NULL
(4 rows)
Alternatively, within the built-in SQL shell, you can use the \du shell command:
> \du
username | options | member_of | estimated_last_login_time
-----------+----------------+-----------+------------------------------
admin | {CREATEROLE} | {} | NULL
carl | {NOLOGIN} | {} | NULL
petee | {} | {} | 2025-08-04 19:18:00.201402+00
root | {CREATEROLE} | {admin} | NULL
(4 rows)
