Not related to the proposed change, this sentence is the same before and
after, but makes me wonder:
> However, <application>psql</application>
will waste a connection attempt finding out that the server wants a
password. In some cases it is worth typing <option>-W</option> to
avoid
the extra connection attempt.
AFAIK, there is nothing in the protocol that forces psql to make an extra
connection attempt. If libpq provided a means to pass a password-prompt
callback, no extra connection would be needed I think?
