Sorry my mail program send the mail to early. Please ignore the line
tableOid = rel->rd_id. I was just deleting the line when google send the
mail :(

resultAsAggState is of the type AggState. As you can see I tried to get the
Oid with the ScanState inside of the AggState, but its Relation
ss_currentRelation is not set already. Is there another way to get the Oid?
