I followed this guide in order to upgrade the plan for postgres:

https://devcenter.heroku.com/articles/updating-heroku-postgres-databases#updating-with-addons-upgrade

I want to upgrade using heroku addons:upgrade.

this is the output:

Changing postgresql-rernd-166744 on myapp-api from heroku-postgresql:hobby-dev to heroku-postgresql:standard-0... !
 !    An error was encountered when contacting the add-on partner to change to heroku-postgresql:standard-0:
 !    heroku-postgresql does not currently support changing plans.

I have added a bank card and already using another heroku plan in another app so I doubt that's the reason.

CodePudding user response：

For any upgrade regarding Hobby plan, you have to use pg:copy, heroku addons:upgrade only work for production tier (new and old database must be on those plans)

CodePudding user response：

The pg:copy command supports updates between all supported Heroku Postgres plans and versions. Additionally, it is the only supported method for updates involving a Hobby-tier database (whether you are migrating to one or from one).

So this is the guide you want to follow in order to upgrade your DB plan
