Committed. I noticed that there are several characters with no match in
protocol.h. It might be worth adding those.
In walsender.c:
1537: pq_sendbyte(ctx->out, 'w');
2353: case 'r':
2357: case 'h':
2361: case 'p':
2755: pq_sendbyte(&output_message, 's');
3367: pq_sendbyte(&output_message, 'w');
4138: pq_sendbyte(&output_message, 'k');
In walreceiver.c:
829: case 'w': /* WAL records */
853: case 'k': /* Keepalive */
1133: pq_sendbyte(&reply_message, 'r');
1237: pq_sendbyte(&reply_message, 'h');
In logical/worker.c:
3854: if (c == 'w')
3876: else if (c == 'k')
3895: else if (c == 's') /* Primary status update */
4127: pq_sendbyte(reply_message, 'r');
4298: pq_sendbyte(request_message, 'p');
