FWIW, I think using -W in interactive commands is a bad habit
that you should drop.  Because it forces a password prompt, it
easily confuses people into thinking that their problem is
password-related whether it actually is or not.

(I notice that with createdb, it actually seems to force *two*
password prompts when there is something wrong.  That's unlike
what happens with psql; maybe we should try to improve that.
But on the other hand, it's hard to get excited about putting
work into improving a behavior that we deprecate using at all.)
