Thank you for reviewing the patch. Yeah, I don't know reproduce the problem too, because some bug of Symantec AntiVirus randomly caused the crash before main()...

Sorry, I couldn't get it. Could you elaborate on it? I couldn't understand how this change has an adverse effect on the postmaster restart process (restart_after_crash = on) and backward compatibility.
Sorry about not providing more details. It is just my doubt, because
I am not able to reproduce the problem to test it after the fix. May be
I can give a try by modifying the source code to get the crash.
My point is, With this patch, in case if the postgres crashses
before reaching main(), does it generate a popup?
If the answer to the above question is yes, then if the popup is
not attended by the DBA, I feel the postmaster is not able to
restart all the processes because it is waiting for the crash process
to close. Am I Correct?
