Django 1.7 Migrations hanging
Worth noting for future readers that the migrations can hang when trying to apply a migration for an incorrect size CharField (DB implementation dependent). I was trying to alter a CharField to be greater than size 255 and it was just hanging. Even after terminating the connections as stated it would not fix it as a CharField of size greater than 255 as that was incorrect with my implementation (postgresql). 
TLDR; Ensure your CharField is 255 or less, if greater change your CharField to a TextField and it could fix your problem!
I have a django migration I am trying to apply.  It gets made fine (it's small, it's only adding a CharField to two different Models.  However when I run the actual migrate it hangs (no failure, no success, just sits).
Through googling I've found that other open connections can mess with it so I restarted the DB.  However this DB is connect to continuously running jobs and new queries do sneak in right away.  However they are small, and last time I tried restarting I THINK I was able to execute my migrate before anything else.  Still nothing.
Are there any other known issues that cause something like this?
