Good idea. I suggest this documentation page: https://www.postgresql.org/docs/current/creating-cluster.html Perhaps something along the line of: It is not supported to manually create, delete or modify files in the data directory, unless they are configuration files or the documentation explicitly says otherwise (for example, <file>recovery.signal</file> for archive recovery).
