Issue Number: close #35181, closes #33966, ref #22079
Problem Summary:
In PR #24282 there was an optimization added to remove conditions that was used when calculating the pruned partitions, but it has issues with index-out-of-range and having other side-effects, like index usage is no-longer possible. The optimization is also very limited, since it only removes one selection/comparison (if it would be fixed to work as expected) and could only be used if the partition range is consisting of a single value. So it is better to remove the optimization.
