Flags that define how allocated pages can be reclaimed.
A BTree can locate some pages even when the tree is broken, but not all. The ones it cannot track must be tracked by the page pool in order to reclaim the storage if the tree breaks. The page can be deleted, but its space not reclaimed.
The page pool will not track these pages, so to retrieve the space the page must be deleted explicitly.
