Subject: Re: [PATCH] Fix hashed ScalarArrayOp semantics for NULL LHS with non-strict comparators

Hi Chengpeng,

Thanks for your report. After reading the code, I find that there is still
an issue even if the LHS is not null and the comparator is strict (make
myinteq always return null, see the attached sql for details).

The main reason is that we did not consider whether the comparator's
return value is null during looking up the hash. Not sure whether this
is a big problem.
