The table itself is extremely difficult to read: it would be more easily readable if the font was monospaced, but its not. I'm reasonably confident that the equal sign is part of the second-to-last operator while the lone @> is the final operator. Mostly I say this because GiST doesn't do straight equality so a lone equal operator isn't valid. David J.
