Well I didn't forget, but I assumed we could use the psql parser to
handle the \^\*\![0-9] (that is likely not the correct regex).

I wouldn't assume that we would be taking it away. The only difference
is that at \^ there would be a number. I am not sure how that effects
anyone using \s anyway since \s picks up all errors etc...

If you mean control-P as in "paste" then I would say... get your hands
off the mouse. The mouse is counter productive and it is faster to do
this:

=> \s
76 SELECT * FROM Foo;
=> !76

Just like bash. I certainly don't have a problem with uses different
characters or the like and am open to any suggestion thereof. The reason
I picked ! was because it is what bash uses. The reason I picked !@ is
because they are right next to each other.
