I should elaborate on my use-case. I'm using PostgreSQL with AWS Lambda, and I'm having an issue where when I get a lot of simultaneous requests, connections stay hanging too long (zombie connections).

To solve this, I would like to switch from using the normal pg to this wrapper: https://github.com/MatteoGioioso/serverless-pg

I have first tried naively to alias pg with yarn yarn add pg@npm:serverless-postgres, which didn't work.

ERROR in ./node_modules/pg-cursor/index.js 3:16-55

Now I decided to install serverless-pg normally and use Slonik's query builder alongside it. My code looks somewhat like this.

import ServerlessClient from 'serverless-postgres';
import { sql } from 'slonik';

const client = new ServerlessClient();

async function handler(event) {
	await client.connect();
	const query = sql`
SELECT something
FROM somewhere`;
	try {

		res = await client.query(query.sql, query.values);
		res = res.rows[0];
	} catch (err) {
		throw new createError(500, 'Failed to execute query', {
			details: err,
		});
	}
	await client.clean();
        // use res!
}

That works. But sadly, I'm limited to the query builder part of Slonik only. I would love to be able to use connection.one(), connection.transaction(), etc. How would you achieve this, could you point me in the right direction?
