I finally got the time to put together some stuff for fti for inclusion in pgsql. I have included a README which should be enough to start using it, plus a BENCH file that describes some timings I have done. Please have a look at it, and if you think everything is OK, I would like it seen included in the contrib-section of pgsql. I don't think I will do any more work in this, but maybe it inspires somebody else to improve on it. Maarten Boekhold
