Turning on the ECHO_HIDDEN feature in psql shows how to do this.

\set ECHO_HIDDEN 1
\du user1
********* QUERY **********
SELECT u.usename AS "User name",
u.usesysid AS "User ID",
CASE WHEN u.usesuper AND u.usecreatedb THEN CAST('superuser, create
database' AS pg_catalog.text)
WHEN u.usesuper THEN CAST('superuser' AS pg_catalog.text)
WHEN u.usecreatedb THEN CAST('create database' AS
pg_catalog.text)
ELSE CAST('' AS pg_catalog.text)
END AS "Attributes",
ARRAY(SELECT g.groname FROM pg_catalog.pg_group g WHERE u.usesysid =
ANY(g.grolist)) as "Groups"
FROM pg_catalog.pg_user u
WHERE u.usename ~ '^user1$'
ORDER BY 1;
**************************

List of users
User name | User ID | Attributes | Groups
-----------+---------+------------+--------
user1 | 100 | | {test}
(1 row)
