Herokuでrails db:migrateができない。

railsのアプリをherokuでデプロイしようとしています。
$git push heroku master
は通るのですが、$ heroku run rails db:migrateが以下のエラーが出続けて通りません。
どなたか原因が想定し得る方がいらっしゃれば、アドバイスいただけないでしょうか。

環境
ClearDBアドオンを利用しmysqlに接続
ruby '2.5.1'

# Warning: The database defined as "test" will be erased and
# re-generated from your development database when you run "rake".
# Do not set this db to the same as development or production.
test:
  <<: *default
  database: hokatsu-ver3_test

# As with config/secrets.yml, you never want to store sensitive information,
# like your database password, in your source code. If your source code is
# ever seen by anyone, they now have access to your database.
#
# Instead, provide the password as a unix environment variable when you boot
# the app. Read http://guides.rubyonrails.org/configuring.html#configuring-a-database
# for a full rundown on how to provide these environment variables in a
# production deployment.
#
# On Heroku and other platform providers, you may have a full connection URL
# available as an environment variable. For example:
#
#   DATABASE_URL="mysql2://myuser:mypass@localhost/somedatabase"
#
# You can use this database configuration with:
#
#   production:
#     url: <%= ENV['DATABASE_URL'] %>
#
production:
  <<: *default
  database: hokatsu-ver3_production
  username: hokatsu-ver3

自己解決

こちら自己解決しました。
一度以下の記事を参考にPostgreSQLの前提でgemやdbymlを記載してしまっており、
https://qiita.com/kazukimatsumoto/items/a0daa7281a3948701c39
それをprobブランチで修正してpushしていたつもりだったのですが、git push heroku masterでプッシュしてしまっており、修正ができていないままmigrateしておりました。。

大変失礼しました。
