Re: the concept of a database cluster

Oh, I didn't mean to imply that I am confused. It is clear that there are two concepts here, sharing a term. I was trying to communicate that the manual does not always make it immediately clear from context which concept is meant in a particular sentence.

A garage is a good analogy. A garage is a container for cars rather than a collection of cars. You wouldn't say "I sold my garage" to mean "I sold my car collection". Containers and collections are different things.

Here's a simple example In our context: "remove the cluster" could mean "delete the folder containing the databases", or "drop the databases". Those actions are not identical. I would think we would want to be clear to our users which we mean.
