Closes #.
Rationale for this change
Aggregate algorithm depends on
aggr_expr.lenandfilter_expr.len()being the same (They are iterated simultaneously withzip). As far as I know, their sizes cannot have different sizes from an SQL query.However, while writing unit tests, one can easily forget this invariant. This PR adds check for this assumption.
What changes are included in this PR?
With this check, I recognized some of the unit tests, didn't consider this invariant. This PR fixes these tests also.
Are these changes tested?
Are there any user-facing changes?
