The pq_send_logicalrep_msg_type() function seemed a bit overkill to me.
The comment in the LogicalRepMsgType enum will sufficiently ensure
nobody is going to accidentally add any bad replication message codes.
And it's not like these are going to be changed often.
Why not simply downcast your enums when calling pq_sendbyte?
There are only a few of them.
e.g. pq_sendbyte(out, (uint8)LOGICAL_REP_MSG_STREAM_COMMIT);
Kind Regards.
