Relation “migration” already exists error while executing yii migrate

If you use PostgreSQL Database and got error
“Relation “migration” already exists error while executing yii migrate”
Just check your config, it seems that you have a mistake in schema section.
Example:

'components' => [
        'db' => [
            'class' => 'yii\db\Connection',
            'dsn' => 'pgsql:host=localhost;dbname=yourdb',
            'username' => 'yourdb_user',
            'password' => 'password',
            'charset' => 'utf8',
            'schemaMap' => [
                'pgsql' => [
                    'class' => 'yii\db\pgsql\Schema',
                    'defaultSchema' => 'public'
                ]
            ], // PostgreSQL
        ],
        'cache' => [
            'class' => 'yii\caching\FileCache',
        ],
