Re: rename a cluster

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.
