**Is your feature request related to a problem or challenge? Please describe what you are trying to do.** There are some predicate include implicit `is not null`. ```sql select * from t1 where c1 > 0; -> select * from t1 where c1 > 0 and c1 is not null; ``` Why do this? Expr in `select expr` and `where expr` is different. Same `expr` in `select` don't include implicit `is not null`. After this, We can do this - eliminate self compare #2252 - convert outer join to inner join #1585 - .... other about predicate -- This is an automated message from the Apache Git Service.
