Comment (by zr):

 It's most probably something to do with the "HAVING SUM" clause
 specifically:
 {{{
 #!python
 >>> list(cursor.execute("SELECT * from thing_thing WHERE thing_thing.cost
 > (?) GROUP BY thing_thing.cost", (0,)))
 Out[26]: [(1, Decimal('1.23')), (2, Decimal('4.56')), (3,
 Decimal('7.89'))]

 >>> list(cursor.execute("SELECT * from thing_thing WHERE thing_thing.cost
 > (?) GROUP BY thing_thing.cost", (Decimal(0),)))
 Out[27]: [(1, Decimal('1.23')), (2, Decimal('4.56')), (3,
 Decimal('7.89'))]

 >>> list(cursor.execute("SELECT * from thing_thing WHERE thing_thing.cost
 > (?) GROUP BY thing_thing.cost", (Decimal('0'),)))
 Out[28]: [(1, Decimal('1.23')), (2, Decimal('4.56')), (3,
 Decimal('7.89'))]

 >>> list(cursor.execute("SELECT * from thing_thing GROUP BY
 thing_thing.cost HAVING SUM(thing_thing.cost) > (?)", (0,)))
 Out[24]: [(1, Decimal('1.23')), (2, Decimal('4.56')), (3,
 Decimal('7.89'))]

 >>> list(cursor.execute("SELECT * from thing_thing GROUP BY
 thing_thing.cost HAVING SUM(thing_thing.cost) > (?)", (Decimal('0.0'),)))
 Out[23]: []
 }}}
