列出索引
\di
List of relations
Schema | Name | Type | Owner | Table
--------+----------+-------+----------+-------
public | idx_date | index | postgres | quote
为何无法显示索引的值?
select idx_date from quote limit 10;
ERROR: column "idx_date" does not exist
LINE 1: select idx_date from quote limit 10;

如何创建一个可以显示值出来的索引呢?
idx_date 这个是索引,和字段并不能用,你不能使用select 来查看索引
