Im trying to connect to timescaledb, which has a session based pooler on top of, but I keep getting FATAL: remaining connection slots are reserved for roles with the SUPERUSER attribute

So I was looking at few places, got a bit confused by Pool from node-postgres and what is the actual usage of it.

Currently I have

import type { Connection } from './postgres.connection';
import type { Options } from 'postgres';

import postgres from 'postgres';

export const timescaleConnection = async <T extends Connection = Connection>(
  options?: Options<T>,
) => {
  const databaseUrl = process.env['TIMESCALE_DATABASE_URL'] ?? '';

  return postgres<T>(databaseUrl, {
    idle_timeout: 20, // 20 seconds
    ...options,
  });
};

What should I be doing? Using Pool or any other method of configuration?
