Recommend Postgres Version for 2025.6 in kubernetes

[addich]

I run authentik in kubernetes.

In the Release Notes for 2025.6
https://version-2025-6.goauthentik.io/docs/releases/2025.6
is written:
The PostgreSQL image is no longer pinned in authentik's default values and has been upgraded from version 15 to 17.

And the linked guide is:
https://docs.goauthentik.io/docs/troubleshooting/postgres/upgrade_kubernetes
but there is no version mentioned.

postgresql:
image:
tag: <NEW_VERSION>

I saw in the docker-compose it is:
docker.io/library/postgres:16-alpine

what is the recommended image tag for Kubernetes?

thank you

Same here.

Downgraded temporary postgres to 15.8.0-debian-12-r18 (then upgraded to pg17) to be able to follow the guide : https://docs.goauthentik.io/docs/troubleshooting/postgres/upgrade_kubernetes

On the "Import the database dump", I get manyyyyyyyy constraints errors as :
ERROR: constraint "guardian_userobjectp_user_id_d5c1e964_fk_authentik" for relation "guardian_userobjectpermission" already exists

All the pods runs, but it looks like all my configuration got wiped (as the import mostly failed) :(

Any clues ?

Thx

authentik needs to be shutdown while you do the import
