FW: clarification for generate join implied equalities

No need to reply the below mail.

I am able to generate the scenario.

One of them is basically when there is an expression involving relations on
one side and Var on other side.

Select * from t1,t2 where t1.c1 + t2.c2 = t1.c3;

Subject: clarification for generate join implied equalities

In function generate_join_implied_equalities_normal(), in which kind of
query it can have all three outer_members, inner_members, new_members set?

There is handling related to that in the same function down which I wanted
to understand.
