Thread: logical replication protocol

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

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

The logical replication protocol builds on the primitives of the
physical streaming replication protocol as stated in the document. The
explanation of 'k' and 'w' messages can be found in the "Streaming
Replication Protocol" section.
