Bug reference: 18781
Logged by: pg group gy The number of returned data bars in a field is inconsistent
Email address: zengxianshu0910(at)163(dot)com
PostgreSQL version: 13.6
Operating system: windows
Description:
我本地有一个表book，数据是4660708条，本地执行
with tmp1 as (
SELECT book_name
FROM book
GROUP BY book_name)
select count(*) from tmp1 ;
每次返回的结果数据每次都不一样，相差大概1到几百，数据库是从服务器dompall下来的，我本地和另一台测试服务器一样的数据库，执行的效果是一样的，都是每次结果不一样，服务器上也是每次执行的结果不一样，可以肯定的是book表是没有被修改过，麻烦有时间
帮忙看下，谢谢。
