Cascading replication
Enables a standby server to replicate from another standby server
Cascading replication
is a form of streaming replication where a standby server replicates from another standby server, rather than directly from the primary, meaning replication changes "cascade" down through a hierarchy of servers.
Cascading replication
was introduced with PostgreSQL 9.2.
