Running rake db:drop db:create db:migrate on Heroku Cedar stack

When I try to run:

heroku run rake db:drop db:create db:migrate

I get the error:

Running rake db:drop attached to terminal... up, run.5 Couldn't drop adsfsadfas : #<ActiveRecord::StatementInvalid: PGError: ERROR:  must be owner of database adsfsadfas : DROP DATABASE IF EXISTS "adsfsadfas">

I am on the Heroku Cedar stack. Am I allowed to drop databases on Heroku?

Thanks!

What does Rails db drop do?

db:drop - Drops the database for the current RAILS_ENV environment. If RAILS_ENV is not specified it defaults to the development and test databases. db:drop:all - Drops the database for all environments. db:migrate - Runs migrations for the current environment that have not run yet.
