PostgreSQL错误函数width_bucket(timestamp with time zone,timestamp without time zone[])不存在

Question

已经解决了问题 - 在这里发帖是因为在我翻译了这篇中文博客文章之前，我一直没有找到解决方案。

ERROR:  function width_bucket(timestamp without time zone, timestamp with time zone[]) does not exist
LINE 3:     width_bucket(
            ^
HINT:  No function matches the given name and argument types. You might need to add explicit type casts.

或者

Error: Failed to prepare query: ERROR:  function width_bucket(timestamp with time zone, timestamp without time zone[]) does not exist
LINE 3: width_bucket(
        ^
HINT:  No function matches the given name and argument types. You might need to add explicit type casts.

Answer 1

解决方案是在系列生成器中指定时区（即下面的with time zone ）：

select generate_series(
       timestamp with time zone '2020-10-02 13:43:00', 
       '2020-10-17 16:15:00', 
       '12 hours'))

.. 或者实际上without time zone是匹配您与系列合并的数据。 使用select pg_typeof(timecolumn) from table limit 1; 报告您的数据是否名义上使用时区。
