- DBAL 3.10, DoctrineBundle 2.19, Doctrine Migrations 3.9 (ORM still 2.20).
- Raw SQL: executeQuery()->fetchAllAssociative() instead of
  execute()/fetchAll() (same associative rows).
- Migration: payment.details type comment json_array -> json (json_array
  no longer exists, the schema introspection failed).
- json_array registered as an alias of json for the old migrations, and
  IdToUuidMigration adapted: a fresh install (all migrations on an empty
  database) works and gives exactly the mapped schema.
- Decimal defaults written as strings, like the database ('0.00').
