Since we're about to push tsearch into core, I'm not very happy with a
"leave it to the future" approach. We need to get the API right *now*.
I think that a function defined as "take these words and do an
appropriate weighted search with them" doesn't necessarily have to
specify what the weighting is. But if the definition is "find the AND
of these words", you can't fudge that later on.
