this TODO:
 * TODO: It sounds like FOR PORTION OF might need to do something here too?
based on comments on ExprContext. I refactor a bit, and solved this TODO.

tring to the following TODO:
// TODO: Need to save context->mtstate->mt_transition_capture? (See
comment on ExecInsert)

but failed.
I also attached the trial, and also added the related test.

You can also use the test to check portion update with insert trigger
with "referencing old table as old_table new table as new_table"
situation.
