Which issue does this PR close?
Rationale for this change
As discussed in the review thread on #20768 and tracked by #20826,
sum_valueshould not keep narrow integer column types during stats aggregation, because merge/multiply paths can overflow before values are widened.What changes are included in this PR?
This PR updates statistics
sum_valuearithmetic to match SUM-style widening for small integer types, and applies that behavior consistently across merge and multiplication paths.Are these changes tested?
Yes
Are there any user-facing changes?
