How to connect to Cloud SQLĭatabase connections consume resources on the server and the connectingĪpplication.If you need to connect to your PostgresSQL database with an SSL certificate using psycopg2, you'll need to put your certificate SSL certificate in a subdirectory of your python program, and then you can reference the certificate in your connection string.

For new instances, this means you must have configured Granting access to an application does not automatically enable a databaseīefore you can connect to an instance, you must have a database user account New customers also get $300 in free credits to spend on Cloud SQL to run, test, and deploy workloads. You can create an account to evaluate how Cloud SQL performs in real-world scenarios.
