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

I'll think about it and try to implement in the next patch version within a few days.

Sorry for delay.

Please look at v4.
I tried to implement all of David's suggestions.
The only addition - "Login" column. I still thinks this is important information to be highlighted.
Especially considering that the Attributes column small enough with a newline separator.

The changes are split into two patches.
0001 - pg_roles view. I plan to organize a new thread for discussion.
0002 - \du command. It depends on 0001 for "Password?" and "Valid until" columns.

Output for superuser:
