> ASOF join was introduced recently by CALCITE-6372
> The implementation parallels the join implementation. However, the function RelOptUtil.pushDownJoinConditions may adjust the join condition. When that happens, the asof matchCondition may need to be adjusted too. This last adjustment is missing, which can cause the matchCondition to be wrong, because the offsets of the RexInputRef fields are not appropriately adjusted.
