I have not done any performance testing of these changes --- does
anyone have specific test scenarios they'd like to try?


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.
