>
> Vectorized expressions have been implemented for UPPER(), LOWER() and
> LENGTH() for strings but they have not been tied through end-to-end to work
> in queries. VectorizationContext needs to be updated to do this.
> Also, LIKE support in VectorizationContext needs to be extended to support a
> string function as an input.
