Current behavior

Currently, we don't have a mechanism to extend default SelectDatabaseOptions with additional custom options. There is only one way how to apply custom SelectDatabaseOptions is override default CRUD methods (list, create, retrieve, etc)

Expected behavior

We need to have a way to extend default SelectDatabaseOptions with custom attributes

Minimal reproduction of the problem with instructions

interface MySelectDatabaseOptions<TRecord, TResult> extends SelectDatabaseOptions<TRecord, TResult>, ListPaginationSelectDatabaseOptions<TRecord, TResult> {}

class TestRepository extends Repository<TestRecord, { idType: string; selectOptions: MySelectDatabaseOptions<TRecord, unknown> }> {}

const listRecords = async (testRepository: TestRepository) => {
  const records = await testRepository.list({
    limit: 20, // <---- should not throw an error
  })
}

What is the motivation / use case for changing the behavior?

It's redundant to create new class which extends Repository and override default types
