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.
