Hello, Thanks a lot for the suggested solutions.
So, I can use WAL-shipping replication from Primary to the Secundary server, but it's only for full replication. Let's call " P " the provider/primary/master and " S " the subscriber/secundary/slave one. For partial replication (not all the tables), the solutions should use a third (intermediate / middle) server which could have both ways flow with the server P but only one way flow towards the server S. For example, a logical replication (pglogical or logical Postgresql replication) between server P and the middle server and then a WAL-shipping replication between middle server and server S. Is that right ? About the " FDW " solution in " an external server " (a middle one), is it possible to integrate the FDW in the P server to avoid the " external server " ? => What about the trigger-based replication systems like Slony or Londiste ; is it really necessary to have a connection or flow from the server S towards the server P ?

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 ?
