I think from a code perspective, you can look at contrib/test_decoding and src\backend\replication\pgoutput to see how to consume changes and send them to the replica. You can refer to docs [1] for SQL functions to consume changes. [1] - https://www.postgresql.org/docs/devel/functions-admin.html#FUNCTIONS-REPLICATION -- With Regards, Amit Kapila.
