Ahoj Jakub,
Just one more idea: could you turn statement logging on in postgresql before you try again? It is in /var/lib/pgsql/data/postgresql.conf log_statement = 'all'

They(VMs) are deleted. So, my situation is this:
I have clean install of ovirt 3.3.0beta with imported VMs from export domain. Everything works except snapshots. But when I restart ovirt mgmt server, VMs will disappear. Right now I am doing hourly backup of DB.

I can not use workaround with converting domain to export domain, because we use iscsi. It would be perfect if I can retake existing domain. Another gap is if I dont detach export domain I can not attach it to new datacenter and I have to manually edit some files. It would be absolutely perfect to do it from ovirt web gui (for example by "force override button") i thought 3.3 allowed for that, but i could be wrong.
Well, I will backup all VMs to export domain, than create snapshot of ovirt and I will try to restart that server if its going to delete VMs from DB. Than I will report back. I think, that remote session will not be possible, but I can be wrong (I hope).

I change it. But I can not restart postgres.
You can restart it only when the engine is down, it will not restart with database connections open.
