Hi
I want do something that can seem a little bit strange: I'm doing a project and I don't want that the executing plan was known by the sistem.
I've got many different query's and some of them are nearly similar. I have to know how many time it takes to postgresql to do my project.

I've been looking for something similar to: alter system flush shared_pool, used in Oracle system, but i haven't found nothing.

Does anybody have any idea to do this?

yours

Cris..
