Bad error message

From -HEAD:

ERROR:  aggregates not allowed in WHERE clause
STATEMENT:  SELECT *                FROM loans l                WHERE id IN (   SELECT max(l.id)
           FROM loans                                        JOIN customers c ON c.id =  
 
l.customer_id                                        JOIN people p ON p.id =  
c.person_id                                    WHERE p.first_name = 'Test person'
GROUPBY l.loan_type_cd                            )        ;
 

The real issue is this:

ERROR:  missing FROM-clause entry for table "l" at character 132
STATEMENT:  SELECT max(l.id)                                            FROM loans
         JOIN customers c ON  
 
c.id = l.customer_id                                                JOIN people p ON  
p.id = c.person_id                                            WHERE p.first_name =  
'Test person'                                            GROUP BY l.loan_type_cd;

And if I change the FROM loans to be FROM loans l, the original  
select does work fine.

Let me know if I need to create a full test case for this...
