PostgreSQL, often simply Postgres, is an object-relational database management system (ORDBMS) with an emphasis on extensibility and standards compliance. PostgreSQL is developed by the PostgreSQL Global Development Group, a diverse group of many companies and individual contributors. It is free and open-source, released under the terms of the PostgreSQL License, a permissive software license.

TLS/SSL setup instructions

  1. Add the database’s certificate in the setup application using instructions in the Adding a certificate section, in the TrustStore settings article.

  2. Restart the Compliance engine.

  3. Create a PostgreSQL connector in Continuous Compliance with the relevant parameters. Upload a properties file for the connector with the following:

    ssl=true
sslmode=verify-full
sslfactory=org.postgresql.ssl.DefaultJavaSSLFactory
To use the verify-full setting (highest security), the PostgreSQL database certificate’s Common Name (CN) field must match the hostname. To check the CN value in the certificate: openssl x509 -in server.crt -text -noout

Google Cloud SQL IAM Authorization setup instructions

To authorize connections from Continuous Compliance in DCTto a Google Cloud SQL PostgreSQL instance, do the following:

  1. Provision a Google Compute Engine running Continuous Compliance. In the compute engine’s settings, enable Cloud SQL in the Identity and API access section.

  2. Create a built-in PostgreSQL connector with the following settings:

    1. Host: 127.0.0.1

    2. Port: 12345

    3. Upload a property file with the following:

      cloudSqlInstance=<connection name of the PostgreSQL instance from the Google Cloud web console>

socketFactory=com.google.cloud.sql.postgres.SocketFactory
