Since "pg_basebackup" uses the non-exclusive backup method, you can run two
such backups concurrently.
However, there is no way to have it run a backup with several parallel processes
to speed up the procedure.
The high availability setup will require thrid-party software, since PostgreSQL
has no built-in clusterware.
