The latest updates are available in the release notes.

How to choose between versions?

It is recommend you look at what versions your applications have been designed for and what are the capabilities of each of the versions. To learn more, read about each version on the official PostgreSQL site:

How to create a particular version in Azure Arc-enabled PostgreSQL server?

At creation time, you have the possibility to indicate what version to create by passing the --engine-version parameter. If you do not indicate a version information, by default, a server group of PostgreSQL version 14 will be created.

Note that there is only one PostgreSQL Custom Resource Definition (CRD) in your Kubernetes cluster no matter what versions we support. For example, run the following command:

kubectl get crds

It will return an output like:

NAME                                                             CREATED AT
dags.sql.arcdata.microsoft.com                                   2021-10-12T23:53:40Z
datacontrollers.arcdata.microsoft.com                            2021-10-13T01:00:27Z

sqlmanagedinstances.sql.arcdata.microsoft.com                    2021-10-12T23:53:37Z

In this example, this output indicates there are one CRD related to PostgreSQL: postgresqls.arcdata.microsoft.com, shortname postgresqls. The CRD is not a PostgreSQL server. The presence of a CRD is not an indication that you have - or not - created a server. The CRD is an indication of what kind of resources can be created in the Kubernetes cluster.
