Regarding to we are in the planning phase of our DB upgrade, we are currently using Keycloak 23 for SSO integration in our application and are considering upgrade AWS Aurora PostgreSQL major upgrade v12.18 to v15.6 as the backend database. We need to confirm the compatibility between these specific versions.  
Environment Details:  
Aurora PostgreSQL Version: 15.6  
Application: Keycloak  
Keycloak Version: 23

Could you please the information following below queries?

- Is AWS Aurora PostgreSQL 15.6 officially compatible with Keycloak 23?

- Is there a compatibility matrix available for different versions of Keycloak and Aurora PostgreSQL?
