Hi,
http://archives.postgresql.org/pgsql-hackers/2009-07/msg00191.php
In line with Robert's suggestion, I submit the signal multiplexing patch
as self-contained one.
This patch provides support for multiplexing SIGUSR1 signal.
The upcoming synchronous replication patch needs a signal, but we've
already used SIGUSR1 and SIGUSR2 in normal backends. This patch
allows reusing SIGUSR1 for that, and for other purposes too if the need
arises.
Regards,
