Connect to Heroku Postgres without SSL validation
If you want to connect to Heroku Postgres, create a data source connection that corresponds to the data source vendor. In this case, you plan to work with PostgreSQL, so you need to create a connection to PosgreSQL. GoLand already include the necessary JDBC driver.
Heroku Postgres requires you to use SSL for the connection. But for establishing a successful SSL connection, you need a certificate that you must upload to your Heroku application. SSL certificates are specific for each Heroku application. To configure these certificates, see the article about Heroku SSL.
If you do not plan to add the certificate in the keystore, you can bypass the server validation with the NonValidatingFactory option and establish an encrypted connection.
In your Heroku account, create an application with the Heroku Postgres add-on.
In settings of the Heroku Postgres add-on, get the database credentials.
To connect to the database, create a data source that will store your connection details. You can do this using one of the following ways:
From the main menu, navigate to and select PostgreSQL.
In the Database tool window ( ) , click the New icon (
) in the toolbar. Navigate to Data Source and select PostgreSQL.
Check if there is a Download missing driver files link at the bottom of the connection settings area. Click this link to download drivers that are required to interact with a database. For a direct download link, refer to the JetBrains JDBC drivers page.
You can find the downloaded JDBC drivers in the GoLand configuration directory.
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 also use your drivers for the database instead of the provided ones. For more information about connecting to a database with your driver, see Add a user driver to an existing connection.
If there is no Download missing driver files link, then you already have the required drivers.
Specify the database connection details. Alternatively, paste the JDBC URL in the URL field.
In Host, Database, User, Password, and Port fields, specify connection details that you received for the Heroku Postgres add-on.
For the reference information about on the General and other tabs of Data Sources and Drivers dialog (Command I), see .
In the SSH/SSL tab of Data Sources and Drivers dialog, select the Use SSL checkbox.
In the Advanced tab of Data Sources and Drivers dialog, change value of the following property:
sslfactory:org.postgresql.ssl.NonValidatingFactory: to allow SSL connections without validating the server certificate.
Ensure that the connection to the database can be established using the provided details. To do that, click the Test Connection link at the bottom of the connection details area.
In case of any connection issues, refer to the Cannot connect to a database page.
(Optional) By default, only the default database is introspected and available to work with. If you also want to work with other databases, in the Schemas tab, select them for the introspection.
Click OK to create the data source.
Find your new data source in the Database tool window (Alt+1) .
To learn more about the Database tool window, see the corresponding reference topic.
To learn how to work with database objects in GoLand, see Database objects.
To write and run queries, open the default query console by clicking the data source and pressing F4.
To view and edit data of a database object, open Data Editor and Viewer by double-clicking the object.
