Internal error: Optimizer rule 'type_coercion' failed due to unexpected
error: Error during planning: Can not find compatible types to compare Boolean
with [Struct([Field { name: "foo", data_type: Boolean, nullable: false,
dict_id: 0, dict_is_ordered: false, metadata: None }]), Utf8]. This was likely
caused by a bug in DataFusion's code and we would welcome that you file an bug

```rust
fn make_session_state() -> SessionState {
let runtime = Arc::new(RuntimeEnv::default());
let config = SessionConfig::new();
let config =
config.set_bool(crate::config::OPT_OPTIMIZER_SKIP_FAILED_RULES, false);
SessionState::with_config_rt(config, runtime)
}
```
