Unexpected error of MAX(NULL) in prepared statement `ERROR: no builtin aggregate for MAX on [unknown]`

Please describe the issue you observed, and any steps we can take to reproduce it:

**To Reproduce**

Hi,

The following test case triggers an unexpected error:

```
SET plan_cache_mode = force_generic_plan;
CREATE TABLE t33 (c0 FLOAT);
INSERT INTO t33 (c0) VALUES(1);
SET SESSION VECTORIZE=off;
PREPARE prepare_query (FLOAT) AS SELECT VARIANCE(9.4834975E7), MAX($1) FROM t33;
EXECUTE prepare_query(NULL::FLOAT);
DEALLOCATE prepare_query;
```

This is the output:
```
> EXECUTE prepare_query(NULL::FLOAT);
ERROR: no builtin aggregate for MAX on [unknown]
```
If I remove one of `SET plan_cache_mode = force_generic_plan;`, `SET SESSION VECTORIZE=off;`, `VARIANCE(9.4834975E7)`, there will be no error.

**Expected behavior**
No error.
