body: <p>I have this simple seeder class but for some reason is only inserting the first element from the array and the command is not returning any error.</p>
  
  <p>Im using Laravel 5.8 and postgres as DB engine.</p>
  
  <pre><code>&lt;?php
  
  use Illuminate\Support\Carbon;
  use Illuminate\Database\Seeder;
  use Illuminate\Support\Facades\DB;
  
  class PermissionsTableSeeder extends Seeder
  {
      public function run()
      {
          DB::table('permissions')-&gt;insert([
              'id' =&gt; 1,
              'name' =&gt; 'list_users',
              'display_name' =&gt; 'List users',
              'description' =&gt; 'Can list all users',
              'created_at' =&gt; Carbon::now()-&gt;format('Y-m-d H:i:s'),
              'updated_at' =&gt; Carbon::now()-&gt;format('Y-m-d H:i:s')
          ],
