39dcfda2dfixed an incorrect reuse of ResultRelInfos for AFTER triggers when the ResultRelInfo needed to have a different ri_RootResultRelInfo. That caused an issue in logical replication apply workers as finish_edata() neglects to call ExecCloseResultRelations() and instead relies on ExecCleanupTupleRouting() to close relations opened during partitioning's tuple routing. Since39dcfda2d, because we may have done some additional table_opens() calls due to having to create an additional ResultRelInfo because of requirements to have a different ri_RootResultRelInfo, we should now be explicitly closing any relations opened on ResultRelInfos in EState's es_trig_target_relations. Since finish_edate() seems to want to avoid calling ExecCloseResultRelations(), add a new external function named ExecCloseTrigTargetRelations().
