Copy postgres databases between Heroku apps.
Say we have a lot of data on our production database and we'd like to replace our staging database with that data. Well, this is how we can do it:
First make a backup of your production database:
heroku pg:backups capture --app PRODUCTIONThen restore the backup (which is on S3) right into your staging database:
heroku pg:backups restore heroku pg:backups public-url --app PRODUCTION DATABASE --app STAGINGWhere DATABASE represents the HEROKU_POSTGRESQL_COLOR_URL of the database you wish to restore to. You may also specify the default application database using DATABASE_URL.

Hi ! Thanks for the article, it helped me a lot through this jungle of commands.
Those commands have evolved a bit since your article was written:
$ heroku pg:backups restore heroku pg:backups public-url --app PRODUCTION DATABASE --app STAGING
Babgyy, thanks for contributing the new commands! I've updated the pro-tip accordingly.
Hi! Thanks for the tip, it was very helpful. But I've found a problem with it, the second Heroku call needs to be wrapped in backticks or $(). So would be something like this:
$ heroku pg:backups restore $(heroku pg:backups public-url --app PRODUCTION) --app STAGINGBest regards.
