Using "SELECT ALL" instead of just "SELECT" on a query that uses a single unflattenable subquery or view in its FROM clause will force the subquery to be manifested into a temporary table rather than run incrementally using a co-routine.

Add the "PRAGMA cell_size_check=ON" command. Closed-Leaf check-in: 2ead43f0 user: drh tags: cell-size-check-pragma
