One weird trick that you can use when your migrations are screwed (file deleted, manually renamed, etc.)

1. Fire up your favourite DB admin tool (eg. PGAdmin3) and browse to the database in question.

3. Make sure that your migration timestamps corresponds with the data in this column. If you have deleted an older migration, delete the corresponding timestamp.
