> Reevaluate size of result/accumulator types of built in sum()+avg() functions

> Reporter: Robert Stupp
>
> I'd like to propose to enlarge the accumulator and result type. Reason is
> simply that an integer overflow is likely to occur especially for these
> "narrow" types. Even just the {{sum()}} of just two {{tinyint}} of {{100}}
> would return {{-56}}, which is just wrong.
> Probably like
> [this|http://www.postgresql.org/docs/9.1/static/functions-aggregate.html].
> If we decide to do so, we should do it in 2.2.
