VACUUM FULL has been rewritten in 9.0 so that it uses the CLUSTER logic,
except that it doesn't require an index.
If you want to do it in earlier versions, you can use a no-op SET TYPE
command, like so:
ALTER TABLE foo ALTER COLUMN bar SET TYPE baz;
assuming that table foo has a column bar which is already of type baz.
