oh wow

ideally? yes. in practice? big nope. How you actually interpret what you're seeing here? does it look like more like optimizer fragility (plans that assume ideal memory conditions)…

From my experience, planning is often the first headache I have to deal with (join order, hash sizing, operator choice), before concurrency and memory even come into play.

Is this true? Has anyone actually tested and confirmed?
