Hi all,

While doing something I should not have done, I have been able to
trigger latch.c with the error of $subject.  Adding in the elog
generated some information about the PID owning the latch and
MyProcPid has made me understand immediately why I was wrong.  Would
there be any objections to add more information in this case?

The attached patch does so.
Thanks,
