I met this issue right on when I first install the Heroku's POSTGRES.app thing. After one morning trial and error i think this one line of code solved problem. As describe earlier, this is because postgresql does not have default role the first time it is set up. And we need to set that.

sovanlandy=# CREATE ROLE postgres LOGIN;

You must log in to your respective psql console to use this psql command.

Also noted that, if you already created the role 'postgre' but still get permission errors, you need to alter with command:

sovanlandy=# ALTER ROLE postgres LOGIN;

Hope it helps!
