Thank you for reply.
In pgpool source code I found this error message raising in
* if backend offers authentication method, frontend could
* close connection
(errmsg("unable to read data from frontend"),
errdetail("EOF encountered with frontend")));
I would like to understand the comment here - "if backend offers
authentication method, frontend could close connection".
Could you clarify comment of this error message?
