Laravel (v5.2.45) Seeder and double quotes

I am trying to use a Laravel (v5.2.45) DB Seeder to initiate a lookups table in a Postgres DB.

When I run it, I get this output:

[Illuminate\Database\QueryException]
SQLSTATE[42703]: Undefined column: 7 ERROR:  column "lkup_type" of relation "syslookups" does not exist
LINE 1: insert into "syslookups" ("lkup_type", "lkup_text") values (...
                               ^ (SQL: insert into "syslookups" ("lkup_type", "lkup_text") values (0, Employee))

Here's the seeder code:

<?php

use Illuminate\Database\Seeder;

class SyslookupsSeeder extends Seeder
{
    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run()
    {
        DB::table('syslookups')->delete();

        DB::table('syslookups')->insert(
            ['lkup_type'=>0, 'lkup_text'=>"Employee"],
            ['lkup_type'=>0, 'lkup_text'=>"Member"],
            ['lkup_type'=>1, 'lkup_text'=>"Open"],
            ['lkup_type'=>1, 'lkup_text'=>"Closed"],
            // .. many more here
            ['lkup_type'=>5, 'lkup_text'=>"Yes"],
            ['lkup_type'=>5, 'lkup_text'=>"No"],
            ['lkup_type'=>6, 'lkup_text'=>"Work Phone"],
            ['lkup_type'=>6, 'lkup_text'=>"Fax"],
            ['lkup_type'=>6, 'lkup_text'=>"Home Phone"],
            ['lkup_type'=>6, 'lkup_text'=>"Cell Phone"]
        );    
    }
}

Any ideas how I can make it NOT use the double quotes? I have tried with double quotes around the table name and column names with same result. The table has a serial column called lkup_id and the default created_at and updated_at columns, do I need to seed those, too?
