@alamb I wasn't able to get a simple sql example to pass, if I convert the
`Expr` to String directly, the literal is wrapped in a type like so.
```
Running
`/home/edmondo/Development/arrow-datafusion/target/debug/examples/plan_to_sql`
thread 'main' panicked at datafusion-examples/examples/plan_to_sql.rs:45:5:
assertion `left == right` failed
left: "((\"a\" < 5) OR (\"a\" = 8))"
right: "a < 5 OR a = 8"
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
```
However, if I use the `expr_to_sql`, the column names are quoted,
```

```
is it the expectation that column names are always quoted?
