Some notes on this version:

1. Did you mean BackendMsgShmemSize()?
    size =3D add_size(size, BackendStatusShmemSize());

2. In docs:=20

<function>pg_cancel_backend</function> ( <parameter>pid</parameter> =
<type>integer</type>, <parameter>message</parameter> <type>test</type> =
<literal>DEFAULT</literal> <literal>''</literal> )

Did you mean <type>text</type>?

3. Windows build failed [0]

4. In src/include/utils/misc/backend_msg.c identification is =
backend_msg.h


Best regards, Andrey Borodin.
