问题
I'm having troubles to connect an existing heroku database to Google Datastudio. I'm trying to add the connection and I get the following:
Access denied, please check your username and password.
Now, I'm 100% sure that I'm correct on those credentials and the problem comes from somewhere else.
I've tried with different setup, either a free or a paid PSQL instance, nothing works.
I've also setup a dummy account on elephantsql and the connection worked the first time without any issue.
Do you have any idea of the cause of that problem?

With February 6, 2018 update Google DataStudio now allows SSL connection with PostgreSQL
If you enable SSL you need to provide client key+cert and server cert, i've used the following tools to generate them:
1.) I've generated a self signed cert + key with openssl for client key + cerficate
openssl req
-newkey rsa:2048 -nodes -keyout client.key
-x509 -days 365 -out client.crt
2.) i've used postgres_get_server_cert.py 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.
