Cause

clean_requirements_on_remove is enabled in /etc/yum.conf

Resolution

1. Edit /etc/yum.repo.d/CarbonBlackUnifiedView.repo

   #baseurl= https://yum.distro.carbonblack.io/enterprise/stable/$releasever/$basearch/
   baseurl=https://yum.distro.carbonblack.io/enterprise/6.2.3-1/x86_64/

3. Save and exit
4. Run `yum clean all`
5. Download the postgresql93 packages

   yum install postgresql93 postgresql93-server postgresql93-libs postgresql93-contrib

6. Start unified view - `service cb-unifiedview start`
7. After services have started successfully, remove postgresql93

   yum remove postgresql93*
