Review comment:
       Thanks Jason, by the way, do you know why approximateEquality is only 
enabled for unOrdered case, and tolerance is always set to 0 for ordered case?
   
   > There is a mechanism built into the test builder for this, you can call 
approximateEquality(tolerance) to avoid changing the SQL of the test to 
accomplish what you want.

> It's work correct for example in case when there is only one aggregation:
> select col1, stddev(col2) FROM(values ('UA', 3), ('USA', 2), ('UA', 3), 
> ('USA', 5), ('USA', 1), ('UA', 9)) x(col1, col2) GROUP BY col1 LIMIT 6;
> Or when it's after other aggregations:
> select col1, SUM(col2), stddev(col2) FROM (values ('UA', 3), ('USA', 2), 
> ('UA', 3), ('USA', 5), ('USA', 1), ('UA', 9)) x(col1, col2) GROUP BY col1 
> LIMIT 6;
> But when we try to put it before an aggregation, like SUM:
> select col1, stddev(col2), SUM(col2) FROM (values ('UA', 3), ('USA', 2), 
> ('UA', 3), ('USA', 5), ('USA', 1), ('UA', 9)) x(col1, col2) GROUP BY col1 
> LIMIT 6;
> It's failed with error:
> SYSTEM ERROR: AssertionError: Type mismatch:
> rowtype of new rel:
> RecordType(CHAR(3) NOT NULL col1, BIGINT $f1, BIGINT $f2, BIGINT NOT NULL 
> $f3, BIGINT $f4) NOT NULL
> rowtype of set:
> RecordType(CHAR(3) NOT NULL col1, BIGINT $f1, BIGINT $f2, BIGINT NOT NULL 
> $f3, BIGINT NOT NULL $f4) NOT NULL
> Same for stddev_samp
