OK, I think I have narrowed the problem a little bit more. This is caused by
a bug in the common subexpression eliminate optimization rule where it rewrites
a column expression with qualifier merged into the field name. See the second
projection at:
```
Projection: abs(Column { relation: Some("8W08BEQUQG"), name: "value" }),
sin(Column { relation: Some("8W08BEQUQG"), name: "value" }), cos(Column {
relation: Some("8W08BEQUQG"), name: "value" }), tan(Column { relation:
Some("8W08BEQUQG"), name: "value" }), asin(Column { relation:
Some("8W08BEQUQG"), name: "value" }), acos(Column { relation:
Some("8W08BEQUQG"), name: "value" }), exp(Column { relation:
Some("8W08BEQUQG"), name: "value" }), ln(Column { relation: None, name:
"BinaryExpr-+Literal1Column-8W08BEQUQG.value" } AS 8W08BEQUQG.value +
Int32(1)), log2(Column { relation: None, name:
"BinaryExpr-+Literal1Column-8W08BEQUQG.value" } AS 8W08BEQUQG.value +
Int32(1)), log10(Column { relation: None, name:
"BinaryExpr-+Literal1Column-8W08BEQUQG.value" } AS 8W08BEQUQG.value +
Int32(1)), random()
Projection: Column { relation: Some("8W08BEQUQG"), name: "value" } +
Int32(1) AS BinaryExpr-+Literal1Column-8W08BEQUQG.value, Column { relation:
None, name: "8W08BEQUQG.value" }
```
