No, that's a compressed row format, not a compressed block format. MySQL's innodb, for example, supports per-row-compression. Its completely ineffective. Block compression in tokdub and myrocks etc is a completely different class. MySQL's innodb also supporta kind of 'page compression' using the file-system's sparse pages. Its also naff. The closest postgres can get is using zfs with compression. Its a lot better than nothing.
