db:structure:dump broken by 8a5a9dc

Hi everyone,

Commit 8a5a9dc removed the dump_schema_information method from the SchemaStatements mixin for connection adapters. This method is called at the end of db:structure:dump, so it can no longer be run. I filed a corresponding ticket at http://rails.lighthouseapp.com/projects/8994-ruby-on-rails/tickets/21-db-structure-dump-broken-by-8a5a9dc -- but now that's it morning and I'm looking at it again, the fix is *probably* simple unless I'm overlooking something.

Removing the call to it @ railties/lib/tasks/databases.rake:260-262 restores my ability to run the task, and my tests, which depended on db:test:clone_structure, are passing as expected.

Is there any reason for db:structure:dump to write the schema versioning data?
