This applies to our storage implementation. In Lakebase architecture storage serves pages and it doesn't always have the most recent version of the page and therefore it reconstructs it on demand.
In the past we relied on Postgres compute to periodically send a full page so reconstructive a page was always a bounded process. Once we turned it off (and got all those perf gains) we got another problem: unbounded page reconstruction which we had to solve separately.
