This will work, but I don't think it's what Ron is getting at.
To be clear, it is not possible to restore a database into an *existing*
cluster using pgBackRest selective restore. This is a limitation of
PostgreSQL file-level backups.
To do what Ron wants you would need to restore it to a new cluster, then
use pg_dump to logically dump and restore it to whatever cluster you
want it in. This still saves time since there is less to restore but is
obviously not ideal.
