Andrew Lamb updated ARROW-12318:
--------------------------------
Description:
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
