heroku migrations refuse to run during deploy

Question

db:migrate doesn't run when I push my app up to migrations. I'm told it's supposed to detect new migrations and execute db:migration during the push/deploy, but that's simply not happening.

Rails 4 app on ruby 1.9.3.

Here's an example where I had two pending migrations. They're not migrated during the deploy, but they do run when I manually kick them off -- something is amiss.

    $ git push heroku master
