 # Database maintenance tasks
 
-Every command should be ran with a prefix, in case of OTP releases it is `./bin/pleroma_ctl database` and in case of source installs it's `mix pleroma.database`.

+    These mix tasks can take a long time to complete. Many of them were written to address specific database issues that happened because of bugs in migrations or other specific scenarios. Do not run these tasks "just in case" if everything is fine your instance.
 
 ## Replace embedded objects with their references
 
 Replaces embedded objects with references to them in the `objects` table. Only needs to be ran once if the instance was created before Pleroma 1.0.5. 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.
