|We're all too familiar with psql's "no response from backend" message.
|Users can't tell what this means, and psql continues prompting for
|commands after it even though the backend is dead and no commands can
|succeed.  It eventually dies on a signal when the dead socket fills
|up.  I extended the message to offer a better explanation and made
|psql exit when it finds the backend is dead.
|
|I also added a short message and newline when the user does a ctl-D so
|it doesn't mess up the terminal display.
