I'm fairly confused about why this would be a good idea, for several
reasons:
* If you have a tendency to make that typo, why would you want a fix that
only affects psql and not any of your other applications? (If you do
want the latter, there are already ways to do it, eg you could remap
SIGQUIT to some other key via stty, or disable core dumps via ulimit.)
* If we put this in, what becomes of people who actually want a core dump,
eg for debugging?
* SIGQUIT is a fairly well-known way to get out of an application when all
else fails. People who aren't familiar with psql's exit commands might
find it pretty unfriendly of us to block this off.
