Yes, I think we should. How about as in the attached?
By the way, code changes I made in the attached are such that a subsequent
patch could implement firing statement-level triggers of all the tables in
a partition hierarchy, which it seems we don't want to do. Should then
the code be changed to not create ResultRelInfos of all the tables but
only the root table (the one mentioned in the command)? You will see that
the patch adds fields named es_nonleaf_result_relations and
es_num_nonleaf_result_relations, whereas just es_root_result_relation
would perhaps do, for example.
Thanks,
Amit
