Review Comment:
Two differences in the schema.
1. qualifier with sq0, sq1..., since I wrap each unnest column with subquery
2. column name, I rename them to col0, col1..., just for simplicity.
@alamb Does it makes sense to skip these two checks and only check the other?
If not, is there an existing API to change the schema for LogicalPlan, so I
can set None to qualifier and create a new field with the original name?
