Blobspace logging

The database server logs blobspace data, but the data does not pass through either shared memory or the logical-log files on disk. The database server copies data stored in a blobspace directly from disk to tape. Records of modifications to the blobspace overhead pages (the free-map and bitmap pages) are the only blobspace data that reaches the logical log.
