Oh dear sweet lords in the many heavens yes. I have literally turned down devops transition and general system administration work before because they refused to use RDS or equivalent service like Compose.io due to internal corporate policy. Life is too short for me to ever babysit another database server through the painful process of a carefully orchestrated rolling capacity upgrade by way of deliberate use of replicas and failover. (Apparently this has gotten better in newer Postgres versions, but it's not been my job to keep on top of the implications of these things for several years now)
