Seems reasonable.

readline automatically turns off if the input is not coming from a
terminal, right?  That seems like the only really compelling reason
to have -n (since you wouldn't want script commands filling your
history or being subject to tab-completion).  I suppose someone who
really hated tab-completion might want a way to turn off just that
feature, though --- is there a way?

BTW, if you need one more item for your psql todo list ;-) ... when
looking at EXPLAIN outputs it's possible to get NOTICE messages that
fill many screensful.  It might be nice if NOTICEs went through the
pager like query results do.
