| How to produce the bug: |
| when a column's _fixed_values exceeds the max_pushdown_conditions_per_column limit, |
| the column will not perform predicate pushdown, but if there are subsequent columns |
| that need to be pushed down, the subsequent column pushdown will be misplaced in |
| _scan_keys and it causes query results to be wrong |
