Just keep low enough = just don’t use PDO caus such “low enouh” has almoust no sense… Thing should not work in this way. We have some feature and this feature work as if it broken. We need this feature to have some special solution IMO to make it look as expected. PDO is old as world thing.
I will refresh this topic until get some answers from EPIC devs. Don’t like such cases when something broken and no one care, just like nothing happened.
