I have a number of queries that need to run each night. I thought that I could do the following:
cd /var/discourse ./launcher enter app su postgres crontab -e ... add my tasks and save ...
but, I get an error:
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
Is this possible?
