Scheduled backups create crontabs with invalid syntax about dokku-postgres HOT 8 CLOSED

It happens only if I call dokku via SSH, like ssh dokku@myhost postgres:backup-schedule myapp "0 4 * * *" myapp-dokku-postgresql-backup. Probably something is wrong with args escaping.

For that reason it would have been better if script was interpreting each part of the cron time definition as a separate argument.

Use single-quotes. Bash will try and expand the * character on the cli if its enclosed in double-quotes.

Note: our documentation here could be improved with an example and a notice. Feel free to pull request that :)

I checked that, with single quotes is the same.

Are you issuing the request over ssh?

from dokku-postgres.

Yes I have written that in my first comment

Gotcha. Well I think you'd need to escape the variables over ssh. As Dokku doesn't control your local ssh, nothing we can do there.

I'd imagine that using flags for each section would also result in the same issue, as you'd still need to escape the variables. Are you thinking of some other way to do this that would be ssh compatible?

@josegonzalez I was also tricked by this. Would you accept a PR on the README file mentioning this?
