I just researched this. In bash, it seems Ctrl+C and Ctrl+D do kind of
the same thing, i.e. exit command:
$ echo '
> bash: unexpected EOF while looking for matching `''
bash: syntax error: unexpected end of file
$ echo '
> ^C
$
so the question is whether it is wise that we have ^C and ^D do
different things on psql, or they should do the same thing. I doubt we
would want to change ^D, so it would be changing ^C to exit, except we
use ^C to cancel a query and return you to a prompt, so I don't see how
we can change that either.
In summary, we are probably can't improve this.
