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.) regards, tom lane
