First import the the sakila dataset
First install necessary PHP extensions
```sh
sudo apt install php-mysql php-pgsql
```
Then install dependencies
```sh
composer install
```
```sh
php index.php > schema.json
```
I can't seem to be able to reproduce the original .sql
The best I got is
```sh
mysqldump sakila --no-data --skip-opt --skip-quote-names --skip-set-charset
```
