Great! The main complaints about pg_basebackup usage in TB clusters
are: (a) it can't be restarted and (b) it can't be parallelized.
AFAICS your proposal doesn't solve them. It would be nice if it can be
solved in future releases (using rsync or another in-house tool is as
fragile as using pg_basebackup).
