If you're getting the above error, the previous connection to Postgres is probably not closed properly and you need to restart postgres:
- On Linux
sudo service postgresql stop
sudo service postgresql start
- On MacOS
pg_ctl -D /usr/local/var/postgres stop
pg_ctl -D /usr/local/var/postgres start
- On Windows
pg_ctl -D "C:\Program Files\PostgreSQL\9.6\data" restart
