Review Comment:
I think we can simplify the test to
```suggestion
# deallocate a plan
statement ok
DEALLOCATE my_plan;
# can't EXECUTE a deallocated plan
statement error Prepared statement \'my_plan\' does not exist
EXECUTE my_plan('Foo', 'Bar');
```
1. Test Deallcocate
2. Test the deallocated query can't be executed.
