That's very important change for text search, because of tsvector storage.
Headline and rank reads a lot of tsvectors. It seems to me that ranking test
will be very clear: rank function reads whole tsvector and returns small amount
of data (just a number).
Another testing focus may be a lossy indexes, like a index over polygons.
