After installing the ovirt 4.2 repository and running engine-setup the upgrade script fails with an error as shown below. [ ERROR ] Postgresql client version is '9.5.9', whereas the version on 'localhost' is '9.2.23'. Please use a PostgreSQL server of version '9.5.9'. Please note the following required changes in postgresql.conf on 'localhost': postgresql.conf is usually in /var/lib/pgsql/data, /var/opt/rh/rh-postgresql95/lib/pgsql/data, or somewhere under /etc/postgresql* . You have to restart PostgreSQL after making these changes. Engine database host []: The setup script is supposed to take care of this automatically however it fails before even attempting to upgrade postgres. Does anybody know how to work around this?
