-- There are no additional steps needed to use this feature with MongoDB
-- For Postgres, you will need to create a cron job using [pgAdmin](https://www.pgadmin.org/docs/pgadmin4/development/pgagent_jobs.html) or similar to call a Postgres function `idempotency_delete_expired_records()` that deletes expired idempotency records. You can find an example script below. Make sure the script has the same privileges to log into Postgres as Parse Server.
