>                 Key: ARROW-12318
>                 URL: https://issues.apache.org/jira/browse/ARROW-12318
>             Project: Apache Arrow
>          Issue Type: Improvement
>          Components: Rust - DataFusion
>            Reporter: Andrew Lamb
>            Priority: Minor
>
> This is a follow on to ARROW-12277
> Background: Support for Min/Max/Sum/Count were added for DataType::Timestamp(*) types in https://github.com/apache/arrow/pull/9970.
> This ticket tracks adding support for Avg, which is slightly more involved as currently Avg assumes the output type is always F64, and in this case I think Avg(timestamp) should also be (timestamp). We should double check what postgres does in this case and follow its example
