A gist showing how to connect and insert to Postgres

nodeJS - insertToPostgres.js

```js
//insertToPostgres.js

const { client } = require('pg');
const config = require('../config.json');

...
const table = 'descriptions';
const fields = 'product_id, product_name, features, tech_specs'
const host = config.host;
const user = config.username;
const pw = config.password;
const db = config.database;
const port = config.port;
const conString = `postgres://${user}:${pw}@${host}:${port}/${db}`;

const client = new Client({
  connectionString: conString,
});
client.connect();

...
const insertQueryText = 'INSERT INTO descriptions (product_id, product_name, features, tech_specs) VALUES ($1, $2, $3, $4) RETURNING *';
const insertQueryValues = [record.productId, record.productName, record.features, record.techSpecs];
client.query(insertQueryText, insertQueryValues)
  .then(res => console.log(res))
  .catch(err => console.error(chalk.red(`There was an error! --> `), err))
...
```
