Bug reference:      19080
Logged by:          Artem Bezborodko
Email address:      doomedseer@gmail.com
PostgreSQL version: 18.0
Operating system:   N/A
Description:        

Starting from 18 version field "Length of message contents in bytes,
including self." should not have predefined value, due to variable key
length. Now it set as (16).

Seems like an oversight, since the docs describe the v3.2 protocol.
I've attached a fix and CC'd the committer to confirm.

This was reported last week on the pgsql-docs list, and has been fixed:

This has been fixed already, since it was reported on the pgsql-docs
list but I didn't see that until it was committed.

about that!
