Heroku Postgresql with Google Datastudio
Since the February 6, 2018 update, Google DataStudio allows SSL connections with PostgreSQL, which is necessary to connect to a database created via Heroku.
To enable SSL you need to provide client key+cert and server cert, which can be accomplished by taking the following steps:
- Generate a self-signed cert + key with openssl for client key + certificate:
openssl req \
-newkey rsa:2048 -nodes -keyout client.key \
-x509 -days 365 -out client.crt
- Use the
postgres_get_server_cert.py
script to get the self-signed server cert from heroku psql:

The problem is that Heroku Postgres requires an SSL connection which doesn't seem possible with Data Studio at the moment. Hopefully Google will add that option soon.
