Oh, my mistake. That means that patch of CompareTSQ should be reverted, because
it change comparing of existing tsquery (it's important for existing btree indexes).

Computing tsquery->size and length of tsquery instead of using stored values
causes the same effect: it will affect existing btree indexes.

However, Btree index over tsquery is not very useful. IMHO, the single purpose
is a guarantee unique of stored tsquery.
