Check if there is a Download missing driver files link at the bottom of the data source settings area. As you click this link, CLion downloads drivers that are required to interact with a database. The IDE does not include bundled drivers in order to have a smaller size of the installation package and to keep driver versions up-to-date for each IDE version.
You can specify your drivers for the data source if you do not want to download the provided drivers. For more information about creating a database connection with your driver, see Add a user driver to an existing connection.
From the Authentication list, select an authentication method.
pgpass: by using the PGPASS file. You can store this file in the user's home directory (for example, /Users/jetbrains/.pgpass). You can read more about the password file in The Password File at postgresql.org.
User & Password: by using your login and password.
Specify database connection details. Alternatively, paste the JDBC URL in the URL field.
To delete a password, right-click the Password field and select Set Empty.
