Actually, as the list of recovery locks is saved in TopMemoryContext, wouldn't it be better to keep a per-cell deletion of the list, which would mean that we'd better do the operation in the reverse order to make things faster with the new list implementation? But that's what Andres points at with CFIs in the middle of one list of the hash table processed? -- Michael
