"password authentication failed for user" after push to Heroku - django

Question

I followed the heroku documentation to install a django app and at first it worked fine. After a day I pushed some changes to the server. After that, I was not able to access the app at all: FATAL: password authentication failed for user "drjstoymyqyarj"
I can not even sync the db anymore:
$ heroku run python manage.py syncdb
Running `python manage.py syncdb` attached to terminal... up, run.1
Traceback (most recent call last):

psycopg2.OperationalError: FATAL: password authentication failed for user "drjstoymyqyarj"
FATAL: password authentication failed for user "drjstoymyqyarj"
I have used the database settings recommended in the heroku doc:
import dj_database_url
DATABASES = {'default': dj_database_url.config(default='postgres://localhost')}
When I check the logs after pushing code to the server, there is a suspicious Process exited with status 143 that I did not notice before. Maybe that has something to do with it?
$ heroku logs

heroku[web.1]: Stopping all processes with SIGTERM

[Edit]
Same error msg with heroku pg:psql. I am however able to open a Django shell with heroku run python manage.py shell, but I can not access any data from within it (same error of course).
[/Edit]
any help with this is appreciated.

Answer 1

Run
heroku config
and see if there are more than 2 heroku dbs configured and also see if DATABASE_URL point to your configured DB. If not, then you can promote your db to default DATABASE_URL by running:
heroku pg:promote HEROKU_POSTGRESQL_GREEN
Where HEROKU_POSTGRESQL_GREEN is your database name, you will see HEROKU_POSTGRESQL_GREEN_URL in your config.
Once your configured database is promoted to default database, you are ready to go.
