Supported versions of PostgreSQL with Azure Arc-enabled PostgreSQL server
The list of supported versions evolves over time as we progress on ensuring parity with PostgreSQL managed services in Azure PaaS. Today, the major version that is supported is PostgreSQL 14.
The latest updates are available in the release notes.
How to choose between versions?
It's recommended 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:

Currently only PostgreSQL version 14 is supported.
There's 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 returns 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 exporttasks.tasks.arcdata.microsoft.com 2021-10-12T23:53:39Z healthstates.azmon.container.insights 2021-10-12T19:04:44Z monitors.arcdata.microsoft.com 2021-10-13T01:00:26Z postgresqls.arcdata.microsoft.com 2021-10-12T23:53:37Z sqlmanagedinstancerestoretasks.tasks.sql.arcdata.microsoft.com 2021-10-12T23:53:38Z sqlmanagedinstances.sql.arcdata.microsoft.com 2021-10-12T23:53:37Z
In this example, this output indicates there is one CRD related to PostgreSQL:
postgresqls. The CRD isn't a PostgreSQL server. The presence of a CRD isn't 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.
