Thank you very much. I was able to (re)set the `engine` user's password in Postgres. Unfortunately, I'm still having trouble unlocking the disks.
The following command produces no output underneath "Locked disks" when I run
this command on the hosted engine VM:
[root@ovirt-engine1 dwhite]# PGPASSWORD=snip
/usr/share/ovirt-engine/setup/dbutils/unlock_entity.sh -t disk -qLocked disks
However, in the oVirt UI, when I try to put the host into maintenance mode I
continue to get the message that there are (3) locked disks (screenshot below).

I've tried the following multiple times:
PGPASSWORD=snip /usr/share/ovirt-engine/setup/dbutils/unlock_entity.sh -t disk
e0f46dc5-7f98-47cf-a586-4645177bd6a2##########################################CAUTION,
this operation may lead to data corruption and should be used with care.
Please contact support prior to running this

proceed? [y/n]yselect
fn_db_unlock_disk('e0f46dc5-7f98-47cf-a586-4645177bd6a2');INSERT 0 1unlock disk
e0f46dc5-7f98-47cf-a586-4645177bd6a2 completed successfully.
Any other ideas?
