PostgreSQL version: 15.8

Description:

When running 
"barman receive-wal pg"
with postgres 15.8.1


I get the following errors.

arman.utils INFO: Cleaning up lockfiles directory.
barman.wal_archiver INFO: No xlog segments found from streaming for pg.
barman.postgres WARNING: Unexpected non zero minor version 12 in 151200

barman.server ERROR: ArchiverFailure:pg_receivewal terminated with error

Error message says that client does not support server version newer than
15.12 but actual version is 15.8.1 which is older

Error also happens when using 15.12.0

directly

There is no such release as "15.8.1"; we stopped using three-part
version numbers years ago.

pg_receivewal is evidently confused by the bogus version value it's
getting.  Where did you get this server from?
