Maybe that argument > is too weak now to justify keeping the docs, but I'm unsure. Fwiw, I saw that syntax somewhere some days back and then went looking what it meant. I did find it in psql's "\h select" and in turn the full SELECT documentation. I guess if the docs had not mentioned it, I would have had to read the grammar, and looking for a non-string in there sounds painful. So it should definitely be kept. Thanks. :) Christoph
