Laurenz suggestion looks good to me with some suggestions. I agree with
Theodor's addition but I would use the same sentence from the source code that
says 'subdirectory under the mount point'. I would also consider and/or modify
pg_basebackup documentation that has a similar option. My suggestion is that
waldir option in both tools has similar sentences. The term 'WAL location' is
not appropriate because this terminology is already used to indicate the LSN. I
would replace it with WAL directory.
