I think it's possible -- with a bit of programming work. I doubt,
however, that it's going to be all that useful. We're already having
trouble categorizing things like IS NULL (function?, operator?, special
construct?). A function index would be quite unreliable ("It's not in
the function index, so it's not supported."). Feel free to add general
index entries for all functions, though.
