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 Credentials and Certificates, you can use secrets if a vault is configured for the platform and the service supports vaults. For information, see Using secrets from vaults in connections.
Choose the method for creating a connection based on where you are in the platform
In a project Click Add to project > 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
Where you can use this connection

Analytics projects
- Cognos Dashboards (Watson Studio)
- Data Refinery (Watson Studio or Watson Knowledge Catalog)
- DataStage (DataStage service)
- Metadata import (Watson Knowledge Catalog)
- Notebooks (Watson Studio). Use the insert-to-code function to get the connection credentials and load the data into a data structure. See Load data from data source connections.
- SPSS Modeler (SPSS Modeler service)
Catalogs
- Platform assets catalog
