Using a custom MariaDb Grammar for Carbon timestamp precision with Laravel, the application crashes when calling `$builder->toRawSql()`

My goal is to store microseconds in a MariaDB database timestamp fields when using a laravel application.

Following the instructions on https://carbon.nesbot.com/laravel/, I created my Grammar class:

<?php

namespace App\Database\Query\Grammars;

use Illuminate\Database\Query\Grammars\MariaDbGrammar as IlluminateMariaDbGrammar;

class MariaDbGrammar extends IlluminateMariaDbGrammar
{
    public function getDateFormat(): string
    {
        return 'Y-m-d H:i:s.u';
    }
}

and on my AppServiceProvides.php, I included the line DB::connection()->setQueryGrammar(new \App\Database\Query\Grammars\MariaDbGrammar());

Then I created a sample artisan command on console.php

Artisan::command('raw', function () {
    dd(DB::table('user')->where('id_user', 'abc')->toRawSql());
});

Running php artisan raw, the application crashes with

 RuntimeException 

  The database driver's grammar implementation does not support escaping values.

      Illuminate\Database\Query\Builder::toRawSql()

Commenting out the line, the program works as expected:

"select * from `user` where `id_user` = 'abc'" // routes/console.php:84

What is the correct way to enable microseconds for MariaDB databases on a laravel 11 application?

Solved by

1. Creating a MariaDbGrammar exactly as described in the question (following the instruction on https://carbon.nesbot.com/laravel/

2. Creating a MariaDbConnection class in my application that extends Illuminate's MariadDbConnection:

class MariaDbConnection extends IlluminateMariaDbConnection
{
    protected function getDefaultQueryGrammar(): MariaDbGrammar
    {
        // this is the Grammar created on the previous step
        ($grammar = new MariaDbGrammar())->setConnection($this);

        return $this->withTablePrefix($grammar);
    }
}

3. On the AppServiceProvider.php, register the connection with the new Connection class:

public function boot(): void
{
    Connection::resolverFor('mariadb', fn(...$args) => new MariaDbConnection(...$args));
}

Done.
