You can't use to_tsquery for this sort of thing, because it tries to
normalize the given words:

regression=# select to_tsquery('holly:*');
 to_tsquery
------------
 'holli':*
(1 row)

If you do this it works:

regression=# SELECT 'hollywood'::tsvector  @@ 'holly:*'::tsquery;
 ?column?
----------
 t
(1 row)

So if you want to use prefix matching, don't normalize.
