Re: Things I don't like about \du's "Attributes" column

Some attributes are arguably important enough to warrant their own column. The most obvious is NOLOGIN, since those roles are generally used for a very different purpose than LOGIN roles. SUPERUSER might be another candidate (though, I much prefer a dedicated "sudo role" than explicit SU on roles).

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@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
