auth/client_postgres.go

Remove concept of usernames. We really have no reason to use usernames, and they're complicating things more than they need to. We're going to keep logins the same, because we want to be able to support OAuth2/OpenID/whatever logins in the future, and keeping a type associated with those logins is probably for the best.
