Review Comment:
Given how subtle this is and the lack of test coverage, I think a comment is
in order:
```suggestion
// figure out where the first dictionary page (or first data page
are)
// note don't use the location of metadata
// <https://github.com/apache/arrow-datafusion/issues/5995>
let col = metadata.column(0);
```
