Managing migrations
I have a migration "x" that when it runs self.up it adds a new column
to a table, and of course when self. down is run it deletes said
table...
After I ran this migration I continued to work and in the process
added a couple other migrations. After a while I realized that the
column migration "x" created was a mistake and I no longer need it. So
I ran rake db:migrate:down
