   If it is a single, standalone server, you can't change `n` from its default value of `1`.
   
   CouchDB won't allow creation of multiple replicas on a single server. To have 5 copies, you'd need at least 5 servers in your cluster.
   
   Also, nowhere do we recommend that `n` should be `q/2`. By default, on a 3-node cluster, CouchDB 2.x creates `q=8, n=3` databases, and 3.x uses `q=2, n=3`.
