Are you by chance running PostgreSQL 17?

If you are using PostgreSQL 17, you are very likely encountering the issue
tracked here: https://github.com/EnterpriseDB/barman/issues/1041. In that
case,
a fix has already been merged and will be included in an upcoming release of
Barman.

As a quick note for the future, the Barman GitHub issues page is the
correct place
to report problems like this directly to the development team. In any case,
I understand
that you raised it here given the context of the original question about
pg_basebackup.

Hope that helps you.

Best regards,
Israel.
