I've tried creating a postgresql resource with an ownerReference set to another resource. This resulted in a failure to create the postgres instance with the following error message:

time="2024-09-27T12:00:14Z" level=info msg="creating a new Postgres cluster" cluster-name=my-namespace/my-postgres pkg=controller worker=5
time="2024-09-27T12:00:14Z" level=warning msg="cluster created failed: could not create master service: services \"my-postgres\" is forbidden: cannot set blockOwnerDeletion if an ownerReference refers to a resource you can't set finalizers on: , <nil>" cluster-name=my-namespace/my-postgres pkg=cluster worker=5

When I don't set an ownerReference on the postgresql resource the cluster creates without issue. Looking at a successfully created cluster I cannot see any ownerReferences set on the svc/my-postgres. The new owner references feature is not enabled in our environment.

No source files or tests are named. Start by reproducing creation of a PostgreSQL resource with an ownerReference on OpenShift 4.15 and trace the master service creation path; done means the cluster is created successfully with that ownerReference while existing creation without one continues to work.
