This reverts commit 4c909d6.

Projects that use random_compat v1 are not compatible with laravel 5.1. So, composer selects laravel/framework v5.1.19 when random_compat was not included at all. Since random_compat v1 and v2 are functionally same, it should allow composer decide which version to install based on what other projects use.

…s to be run (#18882)

* Add missing postgresql-specific operators

* Fix style error

Currently, the defaultFormatter, set in Writer.php adds a `\n` at the end of each log, while the ErrorLogHandler removes that `\n` in its own `getDefaultFormatter()`

ErrorLogHandler.php:60
```php
    /**
     * {@inheritdoc}
     */
    public function getDefaultFormatter()
    {
        return new LineFormatter('[%datetime%] %channel%.%level_name%: %message% %context% %extra%');
    }
```
