 /**
  * It's strange how actions like changing pool's sequence, that updates the post via
  * update_batch and sends only one metatag: 'pool:$id:$seq' and doesn't send old_tags, don't
  * mess up the rest of the tags (because that metatag is discarted, and the post is left without
  * old_tags or any tag).
  * So we're gonna do a workaround for that: if the new tags only contain metatags, we won't
  * take any further action but commit such metatags.
  * We'll use $had_metatags for that.
