Re: psql: Add role's membership options to the \du+ command

Hello,

After playing with cf5eb37c and e5b8a4c0 I think something must be made 
with \du command.

postgres@demo(16.0)=# CREATE ROLE admin LOGIN CREATEROLE;
CREATE ROLE
postgres@demo(16.0)=# \c - admin
You are now connected to database "demo" as user "admin".
admin@demo(16.0)=> SET createrole_self_grant = 'SET, INHERIT';
SET
admin@demo(16.0)=> CREATE ROLE bob LOGIN;
CREATE ROLE
admin@demo(16.0)=> \du

                                    List of roles
  Role name | Attributes                         | Member of
-----------+------------------------------------------------------------+-----------
  admin     | Create role                                                
| {bob,bob}
  bob |                                                            | {}
  postgres  | Superuser, Create role, Create DB, Replication, Bypass RLS 
| {}

We see two bob roles in the 'Member of' column.Strange? But this is correct.

admin@demo(16.0)=> select roleid::regrole, member::regrole, * from 
pg_auth_members where roleid = 'bob'::regrole;
  roleid | member |  oid  | roleid | member | grantor | admin_option | 
inherit_option | set_option
--------+--------+-------+--------+--------+---------+--------------+----------------+------------
  bob    | admin  | 16713 |  16712 |  16711 |      10 | t            | 
f              | f
  bob    | admin  | 16714 |  16712 |  16711 |   16711 | f            | 
t              | t
(2 rows)

First 'grant bob to admin' command issued immediately after creating 
role bob by superuser(grantor=10). Second command issues by admin role 
and set membership options SET and INHERIT.

If we don't ready to display membership options with \du+ may be at 
least we must group records in 'Member of' column for \du command?
