A preprocessed representation that can be compared to tsvector
efficiently.

Now, if you'd asked whether we need *both* tsvector and tsquery,
that'd be a fair question.  I'm not 100% clear on what the differences
are, but they seem pretty subtle.  Do you think that having only
one datatype would be clearer?
