Perhaps more closely to syntax?

regress_du_role0 with admin, inherit, set granted by regress_du_admin

instead of

regress_du_role0 granted by regress_du_admin with admin, inherit, set

From yesterday's discussion, I think two things are important:
- it is advisable to avoid translation,
- there is no sense in the abbreviation (a,i,s), if there are full names
in the 'attributes' column.

So I agree with such changes and plan to implement them.

And one more question. (I think it's better to have it explicitly
rejected than to keep silent.)

What if this long output will be available only for \du+, and for \du
just show distinct (without duplicates)
roles in the current array format? For those, who don't care about these
new membership options, nothing will change.
Those, who need details will use the + modifier.
