Hi,

during the initialization of the nodes in the plan tree (in ExecInitNode in the file execProcnode.c) I want to find out for a node with the type T_Agg which table will be aggregated. I tried the following:

resultAsAggState = ExecInitAgg((Agg *) node, estate, eflags);

if (resultAsAggState)
{
//tableOid = rel->rd_id;
//tableOid = resultAsAggState->ss.ss_currentRelation->rd_id;
}
It would be great to get the Oid of the table, but I would also be satisfied if I could get at least the name of the table. Does anyone know if it is possible to gather these information?

Best regards
Cathleen
