When OR predicates exist in both the main query and the inline view,
and the same predicate is included within the OR predicate,
if OR expansion occurs only on the OR predicate of the main query,
a result value error occurs where duplicate values are output.

Example)
select * from (select * from t1 where c1 > 0 or c1 >= 1) where c1 > 0 or c1 = 2;

During the process where OR expansion is performed on the OR predicate of the main query,
OR expansion is also performed on the OR predicate of the inline view.

At this time, after the OR expansion of the inline view is completed, during the restoration of the predicate created by LNNVL,
LNNVL restoration for the OR predicate of the main query is also performed simultaneously, resulting in omission of the LNNVL predicate and causing the result value error.
