This is the error that fails you. I have a pending patch to make this more
visible in the log [1], need to find time to verify it...
Does this happen on a clean machine? Perhaps 'engine-cleanup' after such
a failed restore is not enough. Please try reinstalling the OS and trying
again.
If it's not an important machine (test/dev/etc), this will probably be
enough, as a faster replacement for a full OS reinstall:
engine-cleanup
systemctl stop postgresql
systemctl stop rh-postgresql95-postgresql
rm -rf /var/lib/pgsql/data /var/opt/rh/rh-postgresql95/lib/pgsql/data
Then try restore again.

Adding also Eli. Eli - perhaps we need to patch engine-backup to ignore
also this error? I think the minimal flow to reproduce is:
engine-setup
engine-backup --mode=backup --file=f1 --log=l1
engine-cleanup
engine-backup --mode=restore --file=f1 --provision-db
--provision-dwh-db --log=l2
Didn't try this myself.

Still no luck:
# engine-backup --mode=restore --file=back_futur --log=log_futur
--provision-db --restore-permissions --provision-dwh-db
Preparing to restore:
- Unpacking file 'back_futur'
Restoring:
- Files
Provisioning PostgreSQL users/databases:
- user 'engine', database 'engine'
- user 'ovirt_engine_history', database 'ovirt_engine_history'
Restoring:
- Engine database 'engine'
FATAL: Errors while restoring database engine
I did a engine-cleanup, try it again but still the same error.

Please try adding to restore command '--providion-dwh-db'. Thanks.
