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

I think we can change the output like this:

postgres=# \du
List of roles
Role name | Login | Attributes | Password | Valid until | Connection limit
-----------+-------+-------------+----------+-------------+------------------
test | | Inherit | | |
test2 | Can | Inherit | Has | |
wenyi | Can | Superuser +| | |
| | Create DB +| | |
| | Create role+| | |
| | Inherit +| | |
| | Replication+| | |
| | Bypass RLS | | |
(3 rows)

And I submit my the patch, have a look?
Yours,
Wen Yi

Per the recent bug report, we should probably add something like (ignored) after the 50 connections for role1 since they are not allowed to login so the value is indeed ignored. 


Hm, but the same logic applies to "Password?" and "Valid until" for role1 without login attribute. The challenge is how to display it for unprivileged users. But they can't see password information. So, displaying 'Valid until' as '(irrelevant)' for privileged users and real value for others looks badly.What can be done in this situation. 0. Show different values as described above. 1. Don't show 'Valid until' for unprivileged users at all. The same logic as for 'Password?'. With possible exception: user can see 'Valid until' for himself.May be too complicated?2. Tom's advise:
Not sure it's worth worrying about
Show real values for 'Valid until' and 'Connection limit' without any hints.3. The best solution, which I can't see now.
