pg_stat_statements table 中缺少 queryid 列

Question

我们有一个 heroku postgres 数据库，它是运行版本 9.6.1

将我们的 pghero 安装升级到最新版本 2.0.2 时，我们遇到了失败，即 pghero 无法在 pg_stat_statements table.[=14= 中找到 queryid 列]

已安装 pg_stat_statements 扩展程序。

Answer 1

事实证明，在 heroku 上升级 postgres 版本并不一定会将扩展更新到最新版本。

通过运行

更新扩展

ALTER EXTENSION pg_stat_statements UPDATE;

已解决问题。
