So I've tried the 'unsupported' mode with MariaDB 10.2.15. I've also tested adding the `json_valid` check constraint (using `db_check` method) and it mostly worked. There is a problem with path...

Great! Thanks for a hint about the new branch.

Hey, for future reference, there's a typo in the issue title and comments. The correct workaround is to set the `DEFER_PYDANTIC_BUILD` environment variable to `0`, not `PYDANTIC_DEFER_BUILD`.
