Further fix for ticket [57c47526c34f01e8]. If a subquery has a result set
...
column of the form "CAST(expr AS NUMERIC)" do not give that column NUMERIC
affinity. NUMERIC affinity always goes to an integer if able, but a CAST
to numeric is a no-op if the input is a number. So the two are not equivalent.

If a subquery has a result column of the form "CAST(... AS NUMERIC)" then
...
give that column no affinity rather than NUMERIC affinity. This is because
casting to numeric preserves real values that could be integers but numeric
affinity does not. By using no affinity on the column, we make the behavior
consistent if the subquery is implemented as a co-routine or is materialized.
