@alamb after some debugging I have found that we could just change [COUNT_STAR_NAME](https://github.com/apache/arrow-datafusion/blob/85046001da91d535f7ea417911cd51944f9820f4/datafusion/core/src/physical_optimizer/aggregate_statistics.rs#L41) to "COUNT(*)" and everything works fine and tests need to be fixed. BTW the problem comes specifically from `aggregate_statistics` and if it doesn't get applied we get a correct column name. E.g.: ``` ❯ select count(*) from (select 1 union select 2); +----------+ | COUNT(*) | +----------+ | 2 | +----------+ 1 row in set. Query took 0.022 seconds. ``` Will create a PR with this fix -- This is an automated message from the Apache Git Service.
