 Multiple SAS offerings require a second PostgreSQL instance referred to as SAS Common Data Store, or CDS PostgreSQL. For more information, see [Common Customizations](https://documentation.sas.com/?cdcId=itopscdc&cdcVersion=default&docsetId=dplyml0phy0dkr&docsetTarget=n08u2yg8tdkb4jn18u8zsi6yfv3d.htm#p0wkxxi9s38zbzn19ukjjaxsc0kl). A list of SAS offerings that require CDS PostgreSQL is provided in [SAS Common Data Store Requirements](https://documentation.sas.com/?cdcId=itopscdc&cdcVersion=default&docsetId=itopssr&docsetTarget=p05lfgkwib3zxbn1t6nyihexp12n.htm#n03wzanutmc6gon1val5fykas9aa). To create and configure an external CDS PostgreSQL instance in addition to the external platform PostgreSQL instance named `default`, specify `cds-postgres` as a second PostgreSQL instance, as shown in the example below.
