sequelize: Memory leak using findAll method

Issue Description

What are you doing?

Iterating over Postgres DB data via findAll method with limit and offset params. Here is the minimal reproducible code:

import { Model } from './models';

void (async () => {
  let currentOffset = 0;

  const queryData = async (offset = 0) => {
    await Model.findAll({
      limit: 10000,
      offset,
    });

    await queryData(currentOffset += 10000);
  };

  await queryData();
})();

What do you expect to happen?

The code runs fine and doesn’t cause memory leaks.

What is actually happening?

Node.js process grows in memory consumption over time and causes a memory leak and process exit.
