> Fix For: 3.2

>
> The next 2 joins, which have different notation, but semantically are the
> same.
> {code:java}
> t1 JOIN t2 ON t1.id = t2.id AND t1.id = 1 <-- can pushdown condition with
> constant into t1 input only
> t1 JOIN t2 ON t1.id = t2.id AND t1.id = 1 AND t2.id = 1 <-- can pushdown
> conditions with constants into both inputs{code}
> Enabling JOIN_PUSH_TRANSITIVE_PREDICATES rule allows planner to push down
> predicate to both inputs in the first case.
> Let's enable the rule.
