Rails - Sep 2008 - rake db:migrate:down?

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
