If we're going to be renaming things, we might wish to consider further changes, such as putting everything that's temporary & not WAL-logged into "pgsql_tmp" directories, so we don't need lists of "directories to exclude" in things like the pg_basebackup-related code. We should really have an independent thread about this though, as it's not what Robert's asking about here. Thanks! Stephen
