Surely you must use backslash commands for this. Or had you forgotten
that ! and @ are legal operator characters in Postgres?
Also, you can't take away the existing functionality of \s. Invent some
other command instead.
But lastly, do we need this at all? It seems like a relatively awkward,
highly error-prone way to do what you can do today with control-P and
re-execute.
