Personally, I'm not too afraid of having an FTS engine outside the database.
Oracle's Intermedia, which has a very powerful/fast FTS engine, uses that
approach.
I could look into how they do the SQL integration, maybe it would yeld some
ideas.
Mark, about that row identifier: OID's are no good for fast find. Maybe you
could use tuple id (TID). But please note that tuple ID's change after a
simple update. It's like the offset of the row inside the table file (and
therefore blazing fast to get to that row again).
One possible idea for SQL integration: can one use index access-method
functions to query the FTS outside the database? Yes, it would require some
work, but the results I guess it would be wonderful. Ok, Tom, not so fast as
an index sitting inside Postgres, but AFAICS that's not going to happen
anytime soon.
