I feel the need to step back and ask, what problem are we solving here?
Your explanation isn't wrong, but I'm not sure why does a psql user need
all these.
I think you wanted to display "is_superuser" and that seems sensible in
the context of \conninfo+, and perhaps even "role" and "in_hot_standby"
would make sense; but the rest of the parameters that libpq stores do
not seem terribly interesting or relevant here.
That leads me to also wonder why don't we change \conninfo to have this
tabular behavior instead of creating a separate command for it. Why do
we need to keep the existing form of \conninfo? To me it seems strictly
less useful, as it is harder to read.
