含sql_identifier 字段analyze表告警分析

问题表象：

表analyze时 提示告警 the tupleDesc analyzed in coordinator is different from tupleDesc which received from datanode。

问题分析：

本地测试，创建测试表

create table t3(id information_schema.sql_identifier, c1 information_schema.sql_identifier, c2 text);

insert into t3 values (1, 1, 1);

对t3表做表分析

提示信息WARNING:  The tupleDesc analyzed in coordinator is different from tupleDesc which received from datanode.
HINT:  Do analyze again for the relation: t3

原因分析：

数据库中dn传上来的类型时1043， 就是varchar，和cn上的不一致

select oid, typname, typbasetype from pg_type where typname = 'sql_identifier';

规避措施：尽量使用字符串来替换sql_identifier 类型
