Answer 1

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:

1. 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

2. Use the postgres_get_server_cert.py script to get the self-signed server cert from heroku psql:

Answer 2

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.

Answer 3

Make sure to run the openssl command on one line to generate the client.key and client.crt in one command. It took me a couple of tries of downloading the certificates (unable to reach host error), but this finally got me connected to Heroku Postgres with GDS.
