Postgres ユーザーとして cron ジョブを実行できますか？

サポート インストール

毎日実行する必要があるクエリがいくつかあります。以下のようにできるかと思ったのですが：

cd /var/discourse
./launcher enter app
su postgres
crontab -e
... タスクを追加して保存 ...

しかし、エラーが発生します：

postgres@EN-Discourse-Forums-app:~$ crontab -e
crontab: installing new crontab
crontab: crontabs/postgres: rename: Operation not permitted
crontab: edits left in /tmp/crontab.7kGYwA/crontab

これは可能でしょうか？

The more “Discourse-way” of doing that would be creating a plugin with the queries as scheduled jobs.

Check this example:

Inside the execute block you can do anything, like this job who runs SQL:

Potentially, yes, but this doesn’t let others who may need to change the behavior of these queries and our servers use something they understand. It is very common to use CRON to run queries.

Did you read How to add a job to cron/anacron when creating Docker container ?
