清理索引元组的ItemData 清理ItemData的方式是,通过deletable数组获取不用清理的ItemData,存放在newitemids数组中,然后直接将newitemids拷贝到索引页面的pd_linp数组中。 调用compactify_tuples清理索引元组的元组实体 compactify_tuples在《PostgreSQL Vacuum—元组删除》中已经介绍过了,此处不再赘述。 索引插入 处理Vacuum...

newitemonleft待插入的index tuple会插入到左边节点还是右边节点。如果分裂点的index tuple与待插入的index tuple相等,那么这个index tuple既可以插入左节点又可以插入右节点,所以需要这个成员来标识index tuple到底插入到哪个节点。 firstright分裂点,firstright及之后的元素都会被移动到新节点。 best_delta左右节点空间差...
