The whole thing is pretty strange. "received fast shutdown request"
means that the postmaster got SIGINT --- a moment's look at the code
proves there is no other possibility. Now what sent it SIGINT?
AFAICS there are only two possible paths: "pg_ctl stop -m fast" or
this little bit of code in win32/signal.c:

/* Console control handler will execute on a thread created
by the OS at the time of invocation */
static BOOL WINAPI
pg_console_handler(DWORD dwCtrlType)
{
if (dwCtrlType == CTRL_C_EVENT ||
dwCtrlType == CTRL_BREAK_EVENT ||
dwCtrlType == CTRL_CLOSE_EVENT ||
dwCtrlType == CTRL_SHUTDOWN_EVENT)
{
pg_queue_signal(SIGINT);
return TRUE;
}
return FALSE;
}

Can any Windows hackers speculate on causes of this?
