On the Data Sources tab in the Data Sources and Drivers dialog, click the Add icon () and select PostgreSQL.
At the bottom of the data source settings area, click the Download missing driver files link. As you click this link, GoLand 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.
