title: Trouble inserting multipolygon into postgres db with postgis extension
body: <p>I have postgres 10 with the postgis 2.4 extension installed. </p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-js lang-js prettyprint-override"><code>db.none(`INSERT INTO resto_poly_sub (foo, bar geom) VALUES $1 $2, 
  ST_Force2D(ST_GeomFromGeoJSON($3))`, restoPolyArray)</code></pre>
  </div>
  </div>
  </p>
  
  <p>Above isn't the full code but I tried to minimize it. </p>
  
  <p>I'm using this to insert my data into the database. It works with points but not MultiPolygons or MultiLineStrings. It will insert all of the data into the db with no errors but when I use a select statement to retrieve the data it comes back with an empty geometry value. </p>
  
  <p>The data that is being inserted, is being pulled from leaflet.</p>
  
  <pre><code>[
     {
        type: 'Feature',
        properties: {
           foo: 17000,
           bar: null
           geom: {
              type: 'MultiPolygon',
              coordinates: [
                 [
                    [ -115.35644531250001, 37.4364847574233 ],
