1、老问题：修复分区剪枝、分区路由未使用正确的collation导致的core问题和剪枝问题
- 修复range、list分区键比较时未指定字符序的问题。
- 修复hash分区键计算hashvalue未使用collation的场景。
2、修复hash分区剪枝时，const->constcollid与分区键不同导致选错分区的问题：
问题分析：getHashPartitionOid中计算hash使用的时const上的collation，const可能由条件中的常量传入，const的collation与分区键不同，应当使用分区键上的collation
修改方案：getHashPartitionOid中无法方便地获取分区键上的collation，所有需要判断分区的const都会调用getTargetType函数，在此函数中处理collation，使返回的collation都与分区键的相同。getTargetType的src参数可能指向条件上的const，不适合直接修改其const，目前copy后修改。
