That seems fairly useless. You still have a name that requires
double quotes, and you can't tell one operator from another, and
you haven't even saved much space because few operator names are
longer than two or three characters.
(I have thought a little about truncating the contents of Consts
to maybe a dozen bytes for this purpose. Those seem much more
likely to be long...)
More generally, though, I absolutely object to giving the JSON
operators some kind of special privilege in this context.
That's totally not per Postgres style, and besides it's not
solving the problem as a whole, but just this one example.
