Thread: Query regarding support of test_decoding and PGReplicationStream with Standby Logical Replication

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 ?


Regards,
