Fix kill() call in elog() so that it gets its own pid by calling getpid().
MyProcPid global variable is set to 0 when postgres starts as a command(not as a backend daemon). This leads issuing SIGQUIT to the process group,not the process itself. As a result, parent sh gets core dumped in theWisconsin benchmark test.
