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 ?
