Hi Alvaro!

Thanks for the comment.
Oops, You are right, I overlooked they are not relids..
I agreed with you and Amit's opinion so I'll send a revised patch on the next mail. :-)

Next patch will be included:
- New columns definition of the view (as above)
- Renamed the phase name: s/acquiring inh sample rows/acquiring inherited sample rows/
- Update document

Thanks,
Tatsuro Yamada
