URL: https://github.com/apache/datafusion/issues/19914
### Describe the bug
While working on DataFusion vector search, I found a potential bug:
This test case will panic (put in
datafusion/core/tests/user_defined/user_defined_table_functions.rs)
```rust
#[tokio::test]
async fn test_udtf_array_type_coercion() -> Result<()> {
let ctx = SessionContext::new();
ctx.register_udtf("f", Arc::new(SimpleCsvTableFunc {}));
let _ = ctx.sql("SELECT * FROM f(ARRAY[0.1, 1, 2])").await?;
Ok(())
}
```
I believe the fix is to add `simplifier.coerce()` before this line:
https://github.com/apache/datafusion/blob/dededf7c78d587afc662c8a06fb949a0bf4d457f/datafusion/core/src/execution/session_state.rs#L1848
