Yeah that is what seems to be the best way. The thing is that I am looking
in the PostgreSQL code for the first time and I am not fully aware of the
data structures or the methods / algos implemented in the project. This
makes the work of finding out whats and whys much more difficult. So I asked

I have gone through the source code a bit but I wanted to know that which
file contains the code that performs the final SLECTION after the optimizer
has created the final plan? I mean which part of the executor is responsible
for the SELCT to be run?
Can someone tell me the file which governs

Thanks for the reply.
So if I am not wrong, I will have to understand the whole querying process
in detail? If it is so, then where do I start from?

If you haven't seen it already, this is a good place to start:
The PostgreSQL documentation (9.0.1) has the following section in section
44.5.1:
The planner preferentially considers joins between any two relations for
which
there exist a corresponding join clause in the WHERE qualification (i.e., for
which a restriction like

Can someone tell me what are 'Join Pairs with no Join clause' ? I am not

Consider
select * from t1, t2, t3 where t1.a = t2.x and t1.b = t3.y;
In theory this query could be done by first joining t2 and t3,

I think I need to look into the Postgres code itself (I am better at code
than documentation). But since I have not been touch with C lately (these
