Hi Kiran,
Are we trying to perform logical replication from create replication slots on a standby server and use logical decoding plugins(JDBC PGReplicationStream API) to stream changes from the standby
Is my understanding correct?
Hi,
I have a question regarding the new feature introduced in PostgreSQL 16 that enables logical replication from a standby server.
Currently, we are using a standalone instance of PostgreSQL 16 and performing logical replication by creating replication slots and utilizing the JDBC replication stream API (PGReplicationStream) with the test_decoding plugin.
Could you please confirm whether this approach of logical replication is supported from a standby system? Specifically, does the standby system support the test_decoding plugin and the JDBC PGReplicationStream API for streaming changes ?
Reference to JDBC Logical replication - https://jdbc.postgresql.org/documentation/server-prepare/#example-96-create-logical-replication-stream
Regards,
Kiran
Thanks
Dinesh
