title: PG::UndefinedTable: ERROR: table "freqs" does not exist
body: <p>In my db folder, I have two migrations that have do do with this. The first is a migration I created to drop a database I made earlier that did not have what I needed.</p>
  
  <pre><code>class DropProductsTable &lt; ActiveRecord::Migration
    def up
      drop_table :freqs
    end
  
    def down
      raise ActiveRecord::IrreversibleMigration
    end
  end
  </code></pre>
  
  <p>The second is the new database I created.</p>
  
  <pre><code>class CreateFreqs &lt; ActiveRecord::Migration
    def change
      create_table :freqs do |t|
        t.string :description
  
        t.timestamps
      end
    end
  end
  </code></pre>
  
  <p>The rake db:migrate works for development, but when I try to migrate Heroku, the error provided in the title occurs. What's happening? I have searched around StackOverflow to no avail.</p>
