	const dbClient = await client.connect();
	// this is where I'm getting errors
	// right now.
	// It says 'Cannot read property 'query' of undefined'
	// documentation says to use pg module...
	// Not sure what I'm doing wrong.
	const result = await dbClient.query('SELECT * FROM public.test_table');
	const results = { 'results': (result) ? result.rows : null};

.connect doesn't actually return anything. You have the client and then you just call .connect() and reuse the same client object:

So in your case:

await client.connect();

const results = await client.query(....);
