I want to get the attribute from an Aggregation node,
where is it?
typedef struct Agg
{
Planplan;
AggStrategy aggstrategy;
intnumCols;/* number of grouping columns */
AttrNumber *grpColIdx;/* their indexes in the target list */
Oid *grpOperators;/* equality operators to compare with */
longnumGroups;/* estimated number of groups in input */
} Agg;
