may cause "numeric field overflow" on PostgreSQL when generate the sql after 
using the rule AggregateJoinTransposeRule.EXTENDED
URL: https://github.com/apache/calcite/pull/1867
 
 
   Pull request for https://issues.apache.org/jira/browse/CALCITE-3866
   As for aggregate function sum, most of the time, its return type is  equal 
to its operand's type, but if its operand's type has precision, the precision 
of the result may be larger than the oeprans's type. So may be we can set 
precision to the Max value if the oeprand's type has precision, especially for 
the type decimal.
