You could use FDW to replicate what you need to an external server from the provider/primary/master to the subscriber/secondary/slave
Using triggers on the master tables that you want to replicate, you can execute the insert/update/delete actions on the secondary tables through the FDW.
With this approach you only need a connection from provider to the subscriber.

Hello,
If, for security reasons, I can't create a connection or a flow from subscriber/secundary/slave towards provider/primary/master, witch replication systems can I use ?
If possible, I would prefer partial replication (only some tables) to full base replication (all instances).
Do trigger-based replication systems (like Slony or Londiste or others) need a connection or flow from subscriber to the provider ?
Thanks in advance
