Hi,
I can confirm that this was the postgresql-jdbc issue.
After doing a downgrade, I succeeded to continue the installation.

All my oVirt  nodes are upgraded, VM’s, Cluster and Datacenter as well.

The reason for not upgrading directly to 4.5, was that it was not GA when we started. 
I will let it run for a moment before going to 4.5

Thanks for a quick response.
Regards, Ingvar

Thanks, Martin. Can you please clarify how you understand this, and
more importantly, add relevant possible errors/warnings/whatever to
the bug, so that people will find it when searching for them? Thanks.

It was just a guess from below error:

2022-04-26 13:52:42,220+02 ERROR [org.jboss.msc.service.fail] (ServerService Thread Pool -- 51) MSC000001: Failed to start service jboss.deployment.subunit."engine.ear"."bll.jar".component.Backend.START: org.jboss.msc.service.StartException in service jboss.deployment.subunit."engine.ear"."bll.jar".component.Backend.START: java.lang.IllegalStateException: WFLYEE0042: Failed to construct component instance
2022-04-26 13:52:42,231+02 ERROR [org.jboss.as.controller.management-operation] (Controller Boot Thread) WFLYCTL0013: Operation ("deploy") failed - address: ([("deployment" => "engine.ear")]) - failure description: {"WFLYCTL0080: Failed services" => {"jboss.deployment.subunit.\"engine.ear\".\"bll.jar

and a fact that they tried to upgrade to 4.4 now when there is this postgresql-jdbc issue.

Also, while we are working on fixing this, perhaps we can temporarily
make the engine require an older version?

E.g.: https://github.com/oVirt/ovirt-engine/pull/316

Didn't test it.

We are still investigating the issue, once we have a complete picture we will address it


Best regards,
