### Describe the bug Queries with FILTER WHERE don't work when parameters are provided. For instance, `SELECT SUM (amount) FILTER (WHERE year = $1) FROM payments` will fail on physical planning. Query like `COUNT (CASE WHEN year = $1 then amount ELSE NULL END)` fails as well. ### To Reproduce ```rust async fn main() -> Result<()> { // generate test memtable with 30 u64 columns and some data let table1 = generate_memtable(30)?; let cfg = SessionConfig::new() .set("datafusion.sql_parser.dialect", "PostgreSQL".into()); let ctx = SessionContext::new_with_config(cfg); ctx.register_table("table1", Arc::new(table1))?; let dataframe = ctx.sql( "select count (f_0) filter (where f_1 > $1) from table1" ).await? .with_param_values(ParamValues::List(vec![ScalarValue::from(10u64)])); // fails here on physical planning: let result = dataframe?.collect().await.unwrap(); let record_batch = result.first().unwrap(); dbg!(record_batch.columns()); Ok(()) } ``` This fails with error: ``` thread 'main' panicked at filter-where-repro.rs:46:45: called `Result::unwrap()` on an `Err` value: Context("type_coercion", SchemaError(FieldNotFound { field: Column { relation: None, name: "count(table1.f_0) FILTER (WHERE table1.f_1 > $1)" }, valid_fields: [Column { relation: None, name: "count(table1.f_0) FILTER (WHERE table1.f_1 > UInt64(10))" }] }, Some(""))) ``` ### Expected behavior _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
