Fix failed in regression_test/suites/query_p0/group_concat/test_group_concat.groovy select group_concat( distinct b1, '?'), group_concat( distinct b3, '?') from table_group_concat group by b2 exception: lowestCostPlans with physicalProperties(GATHER) doesn't exist in root group The root cause is '?' is push down to slot by NormalizeAggregate, AggregateStrategies treat the slot as a distinct parameter and generate a invalid PhysicalHashAggregate, and then reject by ChildOutputPropertyDeriver. I fix this bug by avoid push down literal to slot in NormalizeAggregate, and forbidden generate stream aggregate node when group by slots is empty (cherry picked from commit e7d6697)
