I don't think we can use "Can" to mean "yes". That's going to be
really confusing.

I don't like (irrelevant) either. I know Tom Lane suggested that, but
I think he's got the wrong idea: we should just display the
information we find in the catalogs and let the user decide what is
and isn't relevant. If I see that the connection limit is 40 but the
user can't log in, I can figure out that the value of 40 doesn't
matter. If I see that the connection limit is labelled as (irrelevant)
I don't know why it's labelled that way and, if it were me, I'd likely
end up looking at the source code to figure out why it's showing it
that way.

I think we should go back to the v4 version of this patch, minus the
(ignored) stuff.
