My Best Regards to all on this Mail List...

I'm using table partition on a large database to improve query performance and vacuum management.
I'm read and understand all in item 5.9 in postgresql online manual.

In my father table, I have all the columns needed and which one is primary key and have a sequence (nextval() funcion as default value of then) associated. On other tables (not inherited from this) I need to have Foreing keys pointing to this table. My doubt and preocupation is about FK check becouse I don't know if PostgreSQL will make a seq scan on all child tables (inherited) to found values, becouse the primary key index is located into father table. I will have a great problem in FK check if seq scan occurs, becouse my father table will take a billion of rows or more.

Is there any other way to solute this? I think the suggested in postgresql manual's items 5.9.2-5.9.4 are not useful for this case.

Thanks...

Lucio
