> Generate multi-byte Unicode characters in addition to regular single byte characters
for random data.
> Don't CAST from STRING/VARCHAR/CHAR TO STRING since all are stored in vectorization without
padding.
> Fix vectorized BETWEEN expression work to avoid unnecessary CAST of DECIMAL constants.
> Fix NULL / Wrong Results issues in VectorElt.
> Change performance Q files to generate non-user EXPLAIN with VECTORIZATION display so
unnecesary CAST / DECIMAL_64 conversions are visible.
