Those two cases are not symmetrical. If you're reading from something
other than a terminal, you certainly don't want interactive mode. If
you ARE reading from a terminal, you might nevertheless want
non-interactive mode. And you CERTAINLY might want -1 when reading a
pipe, as when you do this:

ssh otherhost pg_dump | psql -1 -f -

Currently, this silently fails to deliver the expected behavior.
