Thanks for the reference Tom. I don't follow -hackers, so missed it.

Obviously I disagree with your "it's not useful enough" comment :)

I often lose track of which ROLE is active, in my many
long-lived psql sessions, on various servers (mainly v14 and v16 these days=
),
especially during my recent struggle to adapt our system to v16.
I often resort to \conninfo, but it's less automatic and
harder to visually parse (IMHO) compared to a custom ad-hoc prompt.

Therefore I want to respectfully re-iterate my interest in this enhancement=
.

Thanks, --DD
