If your command line already connected to the correct server/database,
with the correct login role, then yeah you can do that.  If you have to
switch role (say the role that runs the commands is not a login role),
it's not so convenient to disconnect and launch a new psql.

Now of course this not a huge new feature, but a usability improvement
only -- but psql is full of small usability features and they make it a
pleasure to use.
