Not sure about recovering your cluster on a 4.5 install with a 4.4 backup. I would also like to know if that is possible.

As a separate note, if you really need to install 4.4 instead of 4.5; I managed to install a 4.4.10 hosted engine recently by 
- extracting the ova from the ovirt-appliance rpm
- mount the image with guestmount
- do : echo "exclude=postgresql-jdbc" >> /etc/dnf/dnf.conf in the image
- rebuild the ova and point the installer to it when asked for a custom ova path

This stopped the installation playbook from upgrading to the unsupported postgresql-jdbc

It looks like a permanent fix was put in place in 4.5.

Should I consider just bumping up to 4.5 instead of trying to reinstall 4.4?  Will I be able to recover my cluster from the engine backup?

This came in just as the engine came up.

The final pieces of the puzzle were:

The database@server notation expressed in the logs is cool, but is not how it is expressed to actually connect. That threw up a red herring.
I had to create all of the postgres users
Postgres ident authentication requires an ident server such as oidentd. It used to be installed by default, but must be installed after the fact by the system admin now.

Your guess about a not-clean system is not too far off.  Just before this email came in I hit a snag with the CA and key generation. I ran engine-cleanup, then ran engine-setup again, and now the non-UI functions of the engine are (apparently) back up.

Now the engine is running, but the web gui is throwing 500 errors. Internet cut out so I'll get back to it in the morning.
