Hackers,
Should the following paragraph in the docs be modified to point out minimum server version of v17 for incremental backups?
pg_basebackup works with servers of the same or an older major version, down to 9.1. However, WAL streaming mode (-X stream) only works with server version 9.3 and later, and tar format (--format=tar) only works with server version 9.5 and later.
