Quite true. One additional reason for this change is to make SIGQUIT
do something a little closer to what one would expect, ie, force-quit
the backend, and in particular to ensure that SIGQUIT'ing the whole
postmaster-and-backends process group produces a reasonable result.
We've been gradually rationalizing the signal usage over the last few
releases, and this is another step in the process.
