I've been diving more and more into Node.js and hosting services like Heroku and Nodejitsu recently and have been trying to figure out how to best deploy database changes for postgres or mysql.

There are a few migration projects under npm that I can see; however, all seem to be really buggy or just not work. I currently manage the Monarch migration project on npm, but it's currently buggy itself and my experiences developing such utilities are in other, more procedural, languages.

So what do people use to deploy changes to their databases on these environments? What has worked for people?

I'm looking for a better understanding of what the current situation/process looks like.
