22683	Schema tests and .extra queryset method	Maximiliano Robaina	nobody	"Running schema tests I caught an issue, more precisely, in test_add_field_default_transform.
At the end, this test method is doing:

self.assertEqual(Author.objects.extra(where=[""thing = 1""]).count(), 2)

The problem here is what in this where clause, the ""thing"" field must be quoted.

In firebird :

    SELECT * FROM AUTHOR WHERE thing = 1   <-- Here thing (in lowercase) and THING (in uppercase) are equivalent, are the same object

is different of:
   
    SELECT * FROM AUTHOR WHERE ""thing"" = 1   <--  field is quoted

For a more generic test I think we need to avoid use .extra method or another raw sql statement.
