func (d Datasource) UpdateLedger(id, name string) (*model.Ledger, error) {
	// First, check if the ledger exists
	existingLedger, err := d.GetLedgerByID(id)
	if err != nil {
		return nil, err
	}

	// Update the ledger name
	_, err = d.Conn.ExecContext(context.Background(), `
		UPDATE ledgerforge.ledgers
		SET name = $1
		WHERE ledger_id = $2
	`, name, id)
	if err != nil {
		pqErr, ok := err.(*pq.Error)
		if ok {
			switch pqErr.Code.Name() {
			case "unique_violation":
				return nil, apierror.NewAPIError(apierror.ErrConflict, "Ledger with this name already exists", err)
			default:
				return nil, apierror.NewAPIError(apierror.ErrInternalServer, "Database error occurred", err)
