How to rake db:drop and rake db:create on Heroku? [duplicate]

Answer 1

The pg:reset command will recreate the database for you. Example usage:

$ heroku config | grep POSTGRESQL
HEROKU_POSTGRESQL_RED_URL: postgres://somedatabaseurl
$ heroku pg:reset HEROKU_POSTGRESQL_RED_URL
!    WARNING: Destructive Action
!    This command will affect the app: myappname
!    To proceed, type "myappname" or re-run this command with --confirm
> myappname
Resetting HEROKU_POSTGRESQL_RED_URL (DATABASE_URL)... done

The db:reset command would try to drop the database, which is not something that Heroku's permissions allow.
