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.

    * 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.
