Before we can start automatically purging statistics, we must make sure to not lose any important statistical data.

Currently pseudonymizing statistics only targets statistics.type of issue, renew, return and onsite_checkout, while there are other types of statistics like item_found, item_lost, localuse, writeoff and payment. These other types would currently not be migrated into pseudonymized_transactions (See Bug 32438, and Bug 34628) and would automatically be deleted by cleanup_database as there is currently no way of selecting which types to delete or keep.

Also, Koha::Statistics->pseudonymize() currently demands statistics.borrowernumber to exist. This means statistics rows with no borrowernumber are not converted into pseudonymized transactions yet.
