The behavior of rake db:migrate:down is a little bit unexpected (to me  
at least).

If I do this:  
$ rake db:version  
Current version: 20080930121212  
$ rake db:migrate:down VERSION=20080930121212

what happens is the schema in that migration is rolled back, but the  
migration version is NOT removed from schema\_migrations table. So now  
rails _thinks_ the db is at version X (according to schema\_migrations),  
when it fact its schema is _really_ at version X-1.

Am I missing something obvious here? I would have expected  
db:migrate:down to also remove that version from schema\_migrations.

Thanks

$ rake --describe db:migrate:down  
rake db:migrate:down  
Runs the “down” for a given migration VERSION.

You probably want just “db:migrate” with a specific version:

$ rake db:migrate VERSION=20080930121212
