Outdated release! Latest docs are Release 8.2: Create PostgreSQL Connections



You can create connections to one or more PostgreSQL databases from Trifacta®. For more information on PostgreSQL, see


If the Trifacta databases are hosted on a PostgreSQL server, do not create a connection to this database.

  • If you haven't done so already, you must create and deploy an encryption key file for the Trifacta node to be shared by all relational connections. For more information, see Create Encryption Key File


To create this connection:

  • In the Import Data page, click the Plus sign. Then, select the Relational tab. Click the PostgreSQL card. 
  • You can also create connections through the Connections page. 
  • See Connections Page.

For additional details on creating a PostgreSQL connection, see Enable Relational Connections.

This connection can also be created using the API. 

Modify the following properties as needed:

Enter your fully qualified hostname. Example:


PortSet this value to 5432.
Connect String Options

Insert any additional connection parameters, if needed.

Enable SSLSelect the checkbox to enable SSL connections to the database.
DatabaseEnter the name of the database on the server to which to connect.
User NameUsername to use to connect to the database.
PasswordPassword associated with the above username.
Test ConnectionAfter you have defined the connection credentials type, credentials, and connection string, you can validate those credentials.

Connection NameDisplay name of the connection
Connection DescriptionDescription of the connection, which appears in the application.
