PgBouncer Error: prepared statement already exists
I am getting a following error: `You have triggered an unhandledRejection, you may have forgotten to catch a Promise rejection: error: prepared statement "public.rate_limiter:undefined" already exists`.

It seems that the rejection happens during the creation of the limiter:
```js
const rateLimiterHours1 = new RateLimiter.RateLimiterPostgres({
  storeClient: pool,
  points: 250,
  duration: 3600,// 1 hour
  tableName: 'public.rate_limiter',
  keyPrefix: 'limiter_hours_1',
});
```

And I consume this limiter only in one place where it has a catch:
```js
rateLimiterUnion.consume(ip) // union of 1 RateLimiterMemory and 1 RateLimiterPostgres
  .then(_limiter => {
    next();
  })
  .catch((_err) => {
    console.log(_err)
    next(new HTTP429Error())
  });
```

Please feel free to let me know if if I can provide some additional details!
