Docs: Getting Started: Wrap await code in async IIFE

[anishkny]

Before:

const { Client } = require('pg')
const client = new Client()

await client.connect()

const res = await client.query('SELECT $1::text as message', ['Hello world!'])
console.log(res.rows[0].message) // Hello world!
await client.end()

After:

const { Client } = require('pg')
const client = new Client()

(async () => {
  await client.connect()
  
  const res = await client.query('SELECT $1::text as message', ['Hello world!'])
  console.log(res.rows[0].message) // Hello world!
  await client.end()
})();

Great! Closing in favor of brianc/node-postgres-docs#87

FYI the code here is wrong. A semi colon needs to be added before the async function is invoked. See brianc/node-postgres-docs@a9bbef8
