Defined in:

Overview

Drops the replication publication and slot on source, and deletes the local checkpoint database.

Run this after the application has been successfully migrated to the target cluster and you’re confident you won’t need to roll back. The source tables themselves are NOT touched unless –drop-source is passed.

Timeline recommendation:

- Verify the app is healthy on the target cluster
- Wait a few days (or a week) as a rollback window
- Then run `pcrd cleanup`
- Optionally run `pcrd cleanup --drop-source` weeks later
