我有一个Laravel应用程序，运行良好，但由于一些奇怪的原因，日志文件中有很多奇怪的消息：
[2019 - 10 - 04 10：24：21]生产错误：SQLSTATE [HY000][1045]用户"forge'@" localhost"的访问被拒绝（使用密码：否）{"异常"："[对象]（Doctrine\DBAL\驱动程序\PDOException（代码：1045）：SQLSTATE [HY000][1045]用户'forge'@' localhost'的访问权限被拒绝（使用密码：否），网址为/var/www/html/pzw_prod/供应商/教义/dbal/lib/教义/DBAL/驱动程序/PDO连接。php：31，PDO异常（代码：1045）：SQLSTATE [HY000][1045]用户'forge'@' l ocalhost'的访问被拒绝（使用密码：否），位于/var/www/html/pzw_prod/供应商/学说/dbal/lib/学说/数据库应用程序/驱动程序/PDF连接。
问题是，我没有使用名为forge的用户连接到数据库。我的.env使用完全不同的登录名。而且，我重复一遍，一切正常：与数据库的通信按预期工作。数据正在成功读取和写入。
那...为什么日志文件里有这条消息
更新：

更新2：
看起来'forge'是某种默认登录。看起来有时候Laravel没有使用.env中的值。我该如何调试这个？

$ cat config/database.php | grep -B 5 forge
        'mysql' => [
            'driver' => 'mysql',
            'url' => env('DATABASE_URL'),
            'host' => env('DB_HOST', '127.0.0.1'),
            'port' => env('DB_PORT', '3306'),
            'database' => env('DB_DATABASE', 'forge'),
            'username' => env('DB_USERNAME', 'forge'),
--
        'pgsql' => [
            'driver' => 'pgsql',
            'url' => env('DATABASE_URL'),
            'host' => env('DB_HOST', '127.0.0.1'),
            'port' => env('DB_PORT', '5432'),
            'database' => env('DB_DATABASE', 'forge'),
            'username' => env('DB_USERNAME', 'forge'),
