Add a new column
Drop a column
Rename a column
Add an index concurrently (Example), Note: it will still take a long time to run the migration, but it won't write-lock the table.
Drop a constraint (for example, non-nullable)
Add a default value to an existing column

If someone forks a gist and you'd like to merge their changes. Do this:

clone your repo, I use the name of the gist

 git clone git://gist.github.com/1163142.git gist-1163142

add a remote for the forked gist, I'm using the name of my fellow developer
```
 git remote add aaron git://gist.github.com/1164196.git
```

Git hooks for better pivotal integration:

pre-commit:
- prevents commiting on a branch that is not suffixed by an issue number. Some special branches (develop, master) and hotfixes are not constrained
- lints modified python files and exits upon non correctly formatted modules
- other formats (js, scss) have pending code that is not currently called as the workflow for front code is not clear
prepare-commit-msg: prepend issue number to commit message if it's missing and if it is set in the branch name (see pre-commit hook)
post-checkout: [optional] automatically update submodules when checkouting a branch (requires to define the AUTO_SUBMODULE_UPDATE environment variable)

For easy setup:

	# Your init script
	#
	# Atom will evaluate this file each time a new window is opened. It is run
	# after packages are loaded/activated and after the previous editor state
	# has been restored.
	#
	# An example hack to log to the console when each text editor is saved.
	#
	# atom.workspace.observeTextEditors (editor) ->
	# editor.onDidSave ->
