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.
