Comment:
As noted in #23061 the current implementation is problematic on Oracle. It
also does more work than necessary elsewhere: Slicing a query clones it,
which is an expensive operation, and potentially makes the database work
harder.
It is better to implement this as hinted by the ticket's summary -- by
limiting the fetches, not the select.
