Tatsuo, ideallly, I'd like to have tsearch2 untouched, but with
japanese parser(s) and dictionaries (program) available. This is how
tsearch2 was designed. If something prevent to do so, we should improve
tsearch2. This is important now, since we're going to build tsearch2 into
PostgreSQL core for 8.3.
