Hi everybody,

I have started to work on a project that will be implemented on top of Postgresql. Therefore, I have to warm up with postgresql's internals. I downloaded the source code and currently looking at it. But I have some questions?

1. How can I prepare my own query plan? (I will need this because sometimes I can prefer using an index scan of a table or merge-join of two relations. Now I just want to give my own simple query plan.)

2. How can I make postgresql execute my own query plan?

Thanks for the answers.

Baran
