- ## Replace embedded objects with their references
-
- 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.
-
- mix pleroma.database remove_embedded_objects
-
- Options:
- - `--vacuum` - run `VACUUM FULL` after the embedded objects are replaced with their references
-
- ## Prune old objects from the database
-
- mix pleroma.database prune_objects
-
- ## Create a conversation for all existing DMs. Can be safely re-run.
