hosted-engine --deploy --restore-from-file=/opt/engine-backup.dump

If I not use --restore-from-file I can not correctly restore my hosted engine datacenter and cluster. But another DCs restored fine.

[ ERROR ] Failed to execute stage 'Environment setup': Cannot connect to DWH database using existing credentials: ovirt_engine_history@localhost:5432

I know that i can fix problem by editing PostgreSQL pg_hba.conf and set ACLs to trust.

Is any way to customize hosted engine appliance to replace pg_hba.conf to my version?

Is any way to pause deploy proccess and access to hosted engine VM to edit PostgreSQL config?
