RHV 4.2 uses PostgreSQL 9.5 - documentation changes for this were handled in bug 1492549; however, one additional procedure still requires updating: https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.2/html-single/data_warehouse_guide/#Allowing_Read_Only_Access_to_the_History_Database Changes include but might not be limited to (copied from https://bugzilla.redhat.com/show_bug.cgi?id=1492549#c6): - To invoke PostgreSQL utilities you need to start special shell: 'scl enable rh-postgresql95 bash' - Database service has different name 'systemctl start rh-postgresql95-postgresql' - Database configuration files are not in '/var/lib/pgsql/data/', but in '/var/opt/rh/rh-postgresql95/lib/pgsql/data/' (Reported initially by Suyog Sainkar from the CloudForms documentation team. This issue affects the CloudForms documentation by extension - see bug 1608713.)
