Creating test database for alias 'default'...
/srv/virtualenvs/stadtgestalten/lib/python3.4/site-packages/django/db/backends/postgresql/base.py:248: RuntimeWarning: Normally Django will use connection to the 'postgres' database to avoid running initialization queries against the production database when it's not needed (for example, when running tests). Django was unable to create a connection to the 'postgres' database and will use the default database instead.
RuntimeWarning
Got an error creating the test database: permission denied to create database
