Description

The following queries are not supported by DataFusion:

SELECT MAX(b) FROM t GROUP BY a;
SELECT MAX(b) + 1 FROM t GROUP BY a;
SELECT MAX(b + 1) FROM t GROUP BY a;
SELECT a + 1, MAX(b) FROM t GROUP BY a + 1;
SELECT MAX(a) FROM t GROUP BY a;
SELECT * FROM t GROUP BY a, b, c, ...

Add support for these queries.
