I am working with Postgres9.6 with a Master/Slave cluster replication using Streaming replication. I would like to add a new Slave server database but this database with logical replication .

I tried with some configurations but it was not possible :(

Here is the image of what is in my mind: https://github.com/guedim/postgres-streaming-replication/blob/master/resources/images/Database%20Replication.png

Thanks for any help!
