Try:
SELECT spcname, oid, pg_tablespace_location(oid) FROM pg_tablespace
That would require a second connection to the database. You cannot run that query from the walsender session. And that's exactly the issue that Steeve pointed out in his first email.
I think it's better to let pg_basebackup work at the lower level, and then leave it to higher level tools to be able to do the mapping to names.
