It's not the engine that is writing there, it's dwhd. The engine only
reads. Did you check /var/log/ovirt-engine-dwh/ ?

What you did might be enough, in principle, but we do not have it
documented/tested, IIRC.

How did you remove ovirt_engine_history? Did you remove both db and
user? And lines from pghba.conf?

You might need to remove also
/etc/ovirt-engine/engine.conf.d/10-setup-dwh-database.conf , before
running engine-setup. That's the file the engine uses to get
credentials for the dwh db.
