【预置条件】:
1.编译安装单机数据库
2.编译安装插件tidrangescan并创建拓展tidrangescan
【操作步骤】(请填写详细的操作步骤):
1.创建分区表，插入数据
--普通行存range分区表
create table t_tidrangescan_0008_03(c_int1 int,c_varchar varchar default 'test') partition by range(c_int1)(partition p1 values less than(100),partition p2 values less than(500),partition p3 values less than(1001));
create table t_tidrangescan_0008_04(c_int1 int,c_varchar varchar default 'test') partition by range(c_int1)(partition p1 values less than(100),partition p2 values less than(maxvalue));
--普通行存hash分区表,列存，临时行存，全局临时行存不支持
create table t_tidrangescan_0008_05(c_int1 int,c_varchar varchar default 'test') partition by hash(c_int1)(partition p1);
--普通行存list分区表,列存，临时行存，全局临时行存不支持
create table t_tidrangescan_0008_06(c_int1 int,c_varchar varchar default 'test') partition by list(c_int1)(partition p1 values(1),partition p2 values(2),partition p3 values(3));
--间隔行存range分区表
create table t_tidrangescan_0008_07(c_date date,c_varchar varchar default 'test') partition by range(c_date) interval ('1 day' )
(partition p1 values less than ('1900-01-01 00:00:00'));
2.调用tidrangescan
show enable_tidrangescan;show enable_seqscan;
set enable_tidrangescan to on;
set enable_seqscan to off;
show enable_tidrangescan;show enable_seqscan;
explain performance select count() from t_tidrangescan_0008_03 where ctid < '(2,0)' and ctid > '(0,0)';
explain performance select count() from t_tidrangescan_0008_04 where ctid < '(2,0)' and ctid > '(0,0)';
explain performance select count() from t_tidrangescan_0008_05 where ctid < '(2,0)' and ctid > '(0,0)';
explain performance select count() from t_tidrangescan_0008_06 where ctid < '(2,0)' and ctid > '(0,0)';
explain performance select count(*) from t_tidrangescan_0008_07 where ctid < '(2,0)' and ctid > '(0,0)';
【预期输出】:
1.建表插入数据成功
2.执行成功，走Tid Range Scan
【实际输出】:
1.建表插入数据成功
2.执行失败：提示【ERROR: could not open file "base/15225/65745": No such file or directory】
【原因分析】:

1. 这个问题的根因
2. 问题推断过程
3. 还有哪些原因可能造成类似现象
4. 该问题是否有临时规避措施
5. 问题解决方案
6. 预计修复问题时间
