Review comment:
My understanding of SINGLE_VALUE is that the output is single value, not the
input. For instance, consider the following query:
SELECT SINGLE_VALUE(a) FROM T GROUP BY b ;
Here, suppose all values of 'b' are the same. Then the SINGLE_VALUE(a) will
produce only 1 value and should be allowed.
