PostgreSQL connection

To access your data in PostgreSQL, create a connection asset for it.

PostgreSQL is an open source and customizable object-relational database.

Supported versions

  • PostgreSQL 8.2+

Create a connection to PostgreSQL

To create the connection asset, you need these connection details:

  • Database name
  • Hostname or IP Address
  • Port number
  • Username and password
  • SSL certificate (if required by the database server)

For Private connectivity, to connect to a database that is not externalized to the internet (for example, behind a firewall), you must set up a secure connection.

Choose the method for creating a connection based on where you are in the platform

In a project Click Assets > New asset > Data access tools > Connection. See Adding a connection to a project.


In a catalog Click Add to catalog > Connection. See Adding a connection asset to a catalog.


In a deployment space Click Add to space > Connection. See Adding connections to a deployment space.


In the Platform assets catalog Click New connection. See Adding platform connections.

Next step: Add data assets from the connection
