Is there a way to delete a ledger ?

Like transactions, a ledger can not be deleted.

Though It's not possible to delete a Ledger / Bucket from the API.
It is although possible to do so in the DB directly:

• you need to Drop the schema

• Delete the line in the _system schema.

(Be aware of the risks of doing such manipulation on the database directly.)We are currently working on a flow to allow this.
