Description of problem:
I attempted to install oVirt Engine on my local machine with a database that does not adhere to the required specifications.
In the error message, I got 'None' instead of what I assumed should have been the machine's name:

"""
[ ERROR ] Please set:
          autovacuum_vacuum_scale_factor = 0.01
          autovacuum_analyze_scale_factor = 0.075
          autovacuum_max_workers = 6
          work_mem = 8192
          max_connections = 150
         in postgresql.conf on 'None'. Its location is usually /var/lib/pgsql/data , or somewhere under /etc/postgresql* .

"""

Version-Release number of selected component (if applicable):
- 1.1.5-0.0.master.20180131143442.git57b0f44.fc27 from the nightly snapshot
- oVirt Engine built from source from commit c67207ad112

How reproducible:
Tried once, happened once

Steps to Reproduce:
Attempt to install oVirt Engine with a misconfured postgresql database. Not sure what other preconditions are required.

Actual results:
'None' appears in the error message

Expected results:
The host name should appear in the error message


Additional info:
Note - I repaired the configuration error and retired, and had the installation fail due to an unrelated issue.
This appears in the attached log, but is not relevant to this BZ.
