This is not an error, more like a warning. GNU tar doesn't not store the full path in the tar file, but a relative
path,as full paths are considered dangerous (easier to overwrite existing data by mistake).

It looks like you are trying to make a filesystem backup while the files are still being updated. In order to make a
filesystembackup you need to either:
- shutdown the database
- run "pg_start_backup" (make SURE that you run pg_stop_backup" when done)
