Is PostgresQL 16 supported or at least fine for Keycloak 23?

[mfuentescas]

We have a Keycloak 23 with PostgreSQL 12 installation. I have migrated this database to PostgreSQL 16 in the Testbed, and it seems to be working fine, nothing wrong in the logs. Will it be okay for Production?

Keycloak 23 isn't supported itself, you should upgrade to the latest Keycloak if you want to recieve support and make sure your deployment stays secure. You can find the supported versions of databases for the latest version of Keycloak in our documentation.
