Обсуждение: 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
pglogicalextension:
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-lifein November of this year. 10.17 is over a year old, and 9.6.1 is almost six years old; the most recent
versionsof 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,
Kaushal

It's best to review the documentation here:
