Hey I need to create a complex index that requires to invoke a function...is there a way to do it with Drizzle? I've tried doing this ```ts export const vector_table = sqliteTable( 'vector_table', { id: integer('id').primaryKey(), text: text('text'), vector: float_32_array('vector', { dimensions: 3 }), }, () => [index('vector_table_vector_index').on(sql`libsql_vector_idx(vector\, 'metric=cosine')`)], ); ``` but it generates the wrong sql
