  # Since [rails pull request #52428][1], `#execute_batch` does not
  # trigger a cache clear anymore. However, `#insert_fixtures_set`
  # relies on that clear to ensure consistency. In the postgresql
  # adapter, this is ensured by a call to `#execute` rather than
  # `#execute_batch` in `#disable_referential_integrity`. Since
  # we are not always calling `#disable_referential_integrity`,
  # we need to ensure that the cache is cleared when running
  # our statements by calling `#execute` instead of `#execute_batch`.
  #
  # [1]: https://github.com/rails/rails/pull/52428
  begin # much faster without disabling referential integrity, worth trying.
