Add Postgres default int4 type to the number map

[billypoke]

The integer column type in postgres is a 4 byte column by default, which is not currently mapped to the Number typescript type. This column would result from invoking $table->integer('foo'); in a laravel migration.

Schema::create('characters', function (Blueprint $table): void {
    ...
    $table->integer('character_id')->unique();
    ...
});

Test script

<?php

declare(strict_types=1);

$model = new \App\Models\Character();

$table = $model->getConnection()
    ->getSchemaBuilder()
    ->getColumns($model->getTable());

dd($table);

Which outputs

Other Columns...
2 => array:9 [
    "name" => "character_id"
    "type_name" => "int4"
    "type" => "integer"
    "collation" => null
    "nullable" => false
    "default" => null
    "auto_increment" => false
    "comment" => null
    "generation" => null
  ]
