pepijnve opened a new issue, #19685:
URL: https://github.com/apache/datafusion/issues/19685
### Describe the bug
When the an aggregation expression has been aliased the original expression
is visible in the logical plan explain output. In the physical output only the
alias is printed making it hard to interpret.
### To Reproduce
Here's an example logic plan constructed using the data frame API. The
problematic line is
```
AggregateExec: mode=Single, gby=[], aggr=[agg]
```
```
Logical plan
============
Aggregate: groupBy=[[]], aggr=[[sum(column1) FILTER (WHERE column2 <=
Int64(0)) AS agg]]
Values: (Int64(1), Int64(100)), (Int64(2), Int64(200)), (Int64(3),
Int64(314))
Optimized logical plan
======================
Aggregate: groupBy=[[]], aggr=[[sum(column1) FILTER (WHERE column2 <=
Int64(0)) AS agg]]
Values: (Int64(1), Int64(100)), (Int64(2), Int64(200)), (Int64(3),
Int64(314))
Physical plan
=============
AggregateExec: mode=Single, gby=[], aggr=[agg]
DataSourceExec: partitions=1, partition_sizes=[1]
```
### Expected behavior
Rather than
```
AggregateExec: mode=Single, gby=[], aggr=[agg]
```
the explain output should show something like
```
AggregateExec: mode=Single, gby=[], aggr=[sum(column1@0) FILTER (WHERE
column2@1 <= Int64(0)) as agg]
```
