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. This is a stop-gap means of controlling the decision to manifest
while we try to work out a better to make that decision automatically.
