Connecting to PostgreSQL

Connecting to PostgreSQL

Authenticating a connection to PostgreSQL enables communication between the two platforms. This must be successfully added before Form Connectors can push or Data Source Connectors can pull data.

Adding

The Data Hub area of the platform is where you can add connections for connectors. Navigate the side menu to Data Hub > Connections.

On the Connections page:

  • Click the ADD CONNECTION button in the top-right-hand corner to bring up a list of connections.
  • Click on the PostgreSQL option to add the connection.

Authenticating

After adding a connection, fill in the required properties and save.

Connection String

Add the PostgreSQL Connection String to be used by connectors to access your database.

You must include the Server, Database, User Id, and Password credentials in the string. The PostgreSQL user specified must have at least CONNECT, USAGE, CREATE, SELECT, INSERT, and DELETE privileges assigned. For the most straightforward configuration, grant all privileges to the user.

Encrypted Connection

PostgreSQL will automatically, by default, encrypt the connection if possible. This option will ensure that the Connector uses SSL encryption for all data sent between the platform and your PostgreSQL server.

Click the SAVE button on the top right to store your configuration and automatically verify the connection.

Additional Info

  • PostgreSQL connections are only available on Premium accounts, and they must be an Administrator-level user to see the option.
  • The default port for PostgreSQL is 5432. You must ensure this port is open on your firewall and is configured to accept connections from our cloud servers.


Troubleshooting Tips

To help you get your PostgreSQL connection working as quickly as possible, we’ve listed some common connection errors that you might encounter and how you can resolve them.

TLS Version Error

If your PostgreSQL connection fails with the error message:

A connection was successfully established with the server, but an error occurred during the login process. (provide: SSL Provider; error: 0 – An existing connection was forcibly closed by the remote host)

The error message suggests that your PostgreSQL server does not support TLS 1.2. 

All communications between our platform and external servers require a minimum support for the TLS 1.2 security protocol.

To remedy this issue, an upgrade/update on your PostgreSQL server might be necessary to enable TLS 1.2 or higher. If this is the case, then you will need to contact your IT team to request this upgrade.

Once your server has been updated, you should see that the Connection will start working.

Check if your database server is configured for TLS 1.2 or higher communication.
