I'm working with a small app on Heroku and I'm wondering if a heroku run rake db:migrate will affect the production database. Any thoughts?

I tried heroku db:pull but the pull stopped midway (not to mention that it screwed up my local db):

Schema:         60% |====================================================================================                                                        | ETA:  00:00:16
Saving session to pull_201207010723.dat..

      </style>

        <p>Application Error</p>
      </iframe>
    </body>
    </html>

Additional notes: local development db is sqlite3 and production db (by Heroku standard is postgresql). The devel db was like that by default and I couldn't find a nice tutorial to convert to postgresql.

Thanks a bunch!

実際に実行heroku run rake db:migrateすると、Heroku 上のデータベースが変更されます。つまり、本番データベースが変更されます。
