Explain, because as I understand it a server = one cluster:

https://www.postgresql.org/docs/9.6/static/app-pg-ctl.html

"The init or initdb mode creates a new PostgreSQL database cluster. A 
database cluster is a collection of databases that are managed by a 
single server instance. This mode invokes the initdb command. See initdb 
for details."

And anything different below the above, I am thinking checking a dev 
cluster against a production cluster.
