13 ## Replace embedded objects with their references

15 Replaces embedded objects with references to them in the `objects` table. Only needs to be ran once. The reason why this is not a migration is because it could significantly increase the database size after being ran, however after this `VACUUM FULL` will be able to reclaim about 20% (really depends on what is in the database, your mileage may vary) of the db size before the migration.
