That would be nice, but probably not that big a deal.

What I think would be more useful is a way to exclude the password if
you didn't need it.

It occurs to me the most flexible thing that could be done here would be
providing a libpq function that spits out JSON connection parameters and
have psql turn that into a variable. It would be easy to feed that to a
SQL statement and do whatever you want with it at that point, including
format it to a connection URI.
