Hi Tom, thanks for the quick reply. I've looked at the break points and you are right there are 7 more bytes with data send with AuthenticationOk message, so I think thats what I need to look at :) (Im sure this is just a confirmation that everything is ok).
May I ask, sequence of bytes after the AuthenticationOk messages is: 0080003; Is this sequence represent BackendKeyData or values for Authentication*** status codes, or Im completely worng and it is realy nothing but confirmation for a frontend how the database applied options passed with start-up packet?
Thanks! Greg.

Yes. You should have gotten it --- the backend is designed to coalesce those messages into a single network packet, so as to avoid extra network traffic. I wonder whether your code is failing to notice additional logical messages arriving in the same bufferload.
