I like this idea.
But what if all the attributes are moved to separate columns?
This solves all issues except the wide output. Less significant attributes
can be moved to extended mode. Here's what it might look like:

postgres(at)postgres(17.0)=# \du
List of roles
Role name | Login | Superuser | Create role | Create DB | Replication
-----------+-------+-----------+-------------+-----------+-------------
admin | no | no | no | no | no
alice | yes | yes | no | no | no
bob | yes | no | no | yes | yes
charlie | yes | no | yes | no | no
postgres | yes | yes | yes | yes | yes
(5 rows)

postgres(at)postgres(17.0)=# \du+
List of roles
Role name | Login | Superuser | Create role | Create DB | Replication | Bypass RLS | Inheritance | Password | Valid until | Connection limit | Description
-----------+-------+-----------+-------------+-----------+-------------+------------+-------------+----------+------------------------+------------------+-------------------------------------------------------------
admin | no | no | no | no | no | no | yes | no | | -1 | Group role without login
alice | yes | yes | no | no | no | no | no | yes | infinity | 5 | Superuser but with connection limit and with no inheritance
bob | yes | no | no | yes | yes | yes | yes | no | 2022-01-01 00:00:00+03 | -1 | No password but with expire time
charlie | yes | no | yes | no | no | no | yes | yes | | 0 | No connections allowed
postgres | yes | yes | yes | yes | yes | yes | yes | yes | | -1 |
(5 rows)

postgres(at)postgres(17.0)=# \x \du+ bob
Expanded display is on.
List of roles
-[ RECORD 1 ]----+---------------------------------
Role name | bob
Login | yes
Superuser | no
Create role | no
Create DB | yes
Replication | yes
Bypass RLS | yes
Inheritance | yes
Password | no
Valid until | 2022-01-01 00:00:00+03
Connection limit | -1
Description | No password but with expire time
