Yes, and? I don't see how this could be a bug. If your authentication method asks for a password, you need to have one.
Yes, I need. I just want to have empty password ("").
If you have resetted it, well, you shouldn't have. Or you really want that your users could connect without a password, and then you need to change your authentication method with trust. But no-one will encourage you to do that.
Why I need to change an auth. method? If I've used a \password command in psql(1) and specified an empty password for my role I need to ask a database admin to change an auth. method? :-) Cool! Please note, psql(1) allow to do it as well as SQL - too.
