当我这样做时

bundle exec rake qc:work

运行queue_calssic，我收到此错误

rake aborted!

当我psql --version时，我得到psql (PostgreSQL) 9.3.5

关于可能出错的任何想法？

Answer 1

你有整个查询吗？最重要的部分是缺失，功能或视图在哪里＆＃34; pid＆＃34;不存在。狂野猜测：您不使用版本9.3，而是使用版本9.3，使用procpid。 pg_stat_activity在9.2版中更改了此列名

使用此查询获取服务器版本：

SELECT version();

可以通过dump-restore或pg_upgrade升级到较新版本。

queue classic返回PG :: UndefinedColumn：ERROR：column＆＃34; pid＆＃34;不存在
