Replication between Master PostgreSQL database version 9.6.1 and Standby/Slave PostgreSQL database version 10.17.
Hi,
Is replication possible between PostgreSQL support Master database
running 9.6.1 version which is a lower version to Standby/Slave running
version 10.17?
I have a datacenter *DC1* which is a production environment and serves live
customer traffic hosting Master PostgreSQL database version *9.6.1* and
Standby/Slave PostgreSQL database version *9.6.1* for storing analytics
data. I am adding the new datacenter *DC2* by referring to
https://docs.apigee.com/private-cloud/v4.51.00/adding-data-center?hl=en
which will install *another additional* *Standby/Slave PostgreSQL database
version* *10.17*.
More details :- https://docs.apigee.com/release/supported-software
Please guide me. Thanks in advance.
Best Regards,
Kaushal

Binary replication is not possible between different major versions. You can do logical replication, using the pglogical extension:
https://github.com/2ndQuadrant/pglogical
(Although not directly related, do note that 9.6 has been past end-of-life for nearly a year, and version 10 will reach end-of-life in November of this year. 10.17 is over a year old, and 9.6.1 is almost six years old; the most recent versions of each are 10.22 and 9.6.24.)
Thanks Christophe for the email and appreciate it. I am not sure if I
understand the difference between binary and logical replication
between PostgreSQL Master and Standby/Slave server.
Please guide me. Thanks in advance.
Best Regards,

It's best to review the documentation here:
