IBM Cloud Pak® for Data Version 4.6 will reach end of support (EOS) on 31 July, 2025. For more information, see the Discontinuance of service announcement for IBM Cloud Pak for Data Version 4.X.
Upgrade to IBM Software Hub Version 5.1 before IBM Cloud Pak for Data Version 4.6 reaches end of support. For more information, see Upgrading IBM Software Hub in the IBM Software Hub Version 5.1 documentation.
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 14.0 and later
- PostgreSQL 13.0 and later
- PostgreSQL 12.0 and later
- PostgreSQL 11.0 and later
- PostgreSQL 10.1 and later
- PostgreSQL 9.6 and later
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 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
Where you can use this connection
You can use PostgreSQL connections in the following workspaces and tools:
Projects
-
AutoAI (Watson Machine Learning)
-
Cognos Dashboards (Watson Studio)
-
Data quality rules (Watson Knowledge Catalog)
-
Data Refinery (Watson Studio or Watson Knowledge Catalog)
-
DataStage (DataStage service). See Connecting to a data source in DataStage.
-
Metadata enrichment (Watson Knowledge Catalog)
-
Metadata import (Watson Knowledge Catalog). For information about the supported product versions and other prerequisites when connections are based on MANTA Automated Data Lineage for IBM Cloud Pak for Data scanners, see the Lineage Scanner Configuration section in the MANTA Automated Data Lineage on IBM Cloud Pak for Data Installation and Usage Manual. This documentation is available at https://www.ibm.com/support/pages/node/6597457.
For metadata import (lineage), advanced metadata import must be enabled and a MANTA Automated Data Lineage license key must be installed. See Installing Watson Knowledge Catalog and Enabling lineage import.
- 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
- Other catalogs (Watson Knowledge Catalog)
- Watson Query service
- You can connect to this data source from Watson Query.
