The cluster's "name" is only the file-system's directory path.
You can easily rename this directory, as long as you pass the relevant directory name to pg_ctl's -D parameter (which tells PostgreSQL which database "cluster" to use.)
It goes without saying, don't move the directory while PostgreSQL is running.

Is there a method to rename a cluster?
Clusters don't have names in the first place.
So, from 16.2 "Creating a Database Cluster"
"...you must initialize a database storage area on disk.
We call this a database cluster."
then, directory = cluster, no?
What I was trying to get at is, is mv of the dir ok or
is there something else that needs to be considered? Thx.
