Hi all,

While playing with custom background workers, I noticed that postmaster
does not notify its registered bgworkers if it receives SIGHUP,
so you have to send a SIGHUP directly to the bgworker process to notify it.
Signal handling is correctly done for SIGQUIT and SIGTERM for shutdown only.
Attached is a patch fixing that, I simply added a call to
SignalUnconnectedWorkers in SIGHUP_handler:postmaster.c.

Regards,
