| // |
| // * records that exist in the database, but aren't associated with object |
| // stores described in the metadata, e.g. if a deletion left behind records |
| // * internal bookkeeping, e.g. tombstones for LevelDB or blob references for |
| // SQLite |

| // Currently, blob contents are ignored and only blob metadata is factored into |
| // the output. |
| // |
| // NB: the entire DB is loaded into a DictValue which can consume a lot of |
| // memory! To cut down on total memory requirements, all values and longer keys |
| // will be hashed. However a database with millions of records could still |
| // be problematic. If/when it's necessary to run this on production databases, |
| // further compression will be required. |

| // For now, this function is a utility for testing only. In the future, it's |
| // likely that this will be used for verifying database migrations in |
| // production. |
