That query isn't going to match that index. You'd need to write
... WHERE to_tsvector('english', product_name) @@ to_tsquery('album');
Basically, you can't rely on a default TS configuration when using the
functional-index approach to text searching, because of the restriction
that index contents can't depend on mutable state.
