I haven't been able to find documentation on the actual messages used in the logical replication protocol ('k' & 'w', lower case). I've figured things out mostly by reading pg_recvlogical.c, but "Read The Fine Source" doesn't seem in line with the way PG usually does it ;-)

Did I miss a doc somewhere in my searches???
