Currently both 'fixDecimalDataTypePhysicalVariations' and
'getVectorExpressionsUpConvertDecimal64' are called when vectorizing TopNKey
operator in 'Vectorizer.java'
{code}
vContext.markActualScratchColumns();
try {
List<ExprNodeDesc> keyColumns = topNKeyDesc.getKeyColumns();
keyExpressions =
vContext.getVectorExpressionsUpConvertDecimal64(keyColumns);
fixDecimalDataTypePhysicalVariations(vContext, keyExpressions);
} finally {
vContext.freeMarkedScratchColumns();
