If `target` is registered in the catalog, fields that need reordering can be
determined via a `DESCRIBE` command or via
`spark.catalog.listColumns(tableName).select("name").as[String].collect()`
We do this occasionally at my work. I can try and take a look to see if
there's a cleaner approach that we might use.
```scala
val targetColumns = spark.sql("DESCRIBE EXTENDED
target").select("col_name").as[String].collect()
spark.sql(s"insert into target select ${targetColumns.mkString(", ")} from
input")
```
