I want to get the attribute from an Aggregation node,

where is it?

typedef struct Agg

{

Plan plan;

AggStrategy aggstrategy;

int numCols; /* number of grouping columns */

AttrNumber *grpColIdx; /* their indexes in the target list */

Oid *grpOperators; /* equality operators to compare with */

long numGroups; /* estimated number of groups in input */

} Agg;
