- to clarify how pg_basebackup works with servers of the same or older major
version
There is no “how”, it just does. The documentation is versioned and “it” means the binary produced by that version.
- to clearly specify pg_basebackup cannot be used for PostgreSQL major
version upgrade
The page clearly states what a backup can be used for and upgrade is not listed.
