Review Comment:
I think this works and handles the special case reasonably
Another way that might be more general purpose would be to coerce the
argument to boolean with
https://docs.rs/datafusion/latest/datafusion/logical_expr/type_coercion/binary/fn.comparison_coercion.html
SO something like
```rust
let predicate = comparison_coercion(DataType::Binary,
predicate.data_type())?;
```

Review Comment:
If you do this case, you'll have to allow the rest of the coercion proceed
