Contributor guide
Research direction
No implementation file or test is named. Start by reproducing the reported SQL query, `select sum(c1)****2 from PCOLLECTION group by c2`, and trace the aggregation-expression handling in Apache Beam SQL. Done means the query executes successfully with the arithmetic expression applied to the aggregate.
