Hi,
http://archives.postgresql.org/pgsql-hackers/2009-07/msg00191.php
In line with Robert's suggestion, I submit non-blocking pqcomm patch
as a self-contained one.
This patch provides support for non-blocking communication between
a frontend and a backend. The upcoming synchronous replication patch
needs this to make walsender send XLOG records and receive a reply
from the standby server concurrently. Specifically, this patch provides
the function to check for a socket by using "select() / poll()", and
the functions to read the data from local buffer instead of the connection.
Regards,
