Thanks Tom.

May I ask in which version this bug is fixed?

This is a known bug in 7.3.2 and before, if there is an idle backend
that hasn't received any user query since it got a SIGUSR2 interrupt.

2003-02-17 21:53  tgl

	* src/backend/commands/async.c (REL7_3_STABLE):
Async_NotifyHandler
	must save and restore ImmediateInterruptOK.  Fixes known problem
	with failure to respond to 'pg_ctl stop -m fast', and probable
	problems if SIGINT or SIGTERM arrives while processing a SIGUSR2
	interrupt that arrived while waiting for a new client query.
