Implemented the Logical Streaming Replication thing are working fine I see the
XLogData message appearing and I'm able to parse them.
But I haven't see any "Primary Keepalive message" yet. I had tried setting the tcp_keepalive_interval, tcp_keepalives_idle both from client runtime paramter and well as from postgresql.conf still no clue of it.
Any information around it?
If it help I had use the wal2json shared_libraries to send json data across in the stream.
