I've hit a bug using Django 1.2.1.
I've a model with date types. Django generates a query like this that
returns the correct results:
SELECT xxx FROM "table" WHERE ("table"."pub_date" >= 2010-01-24 );
If I switch to "lt" or "lte" it gives me nothing, because sqlite seems to
want "'" around the date. You can see for yourself in the following test
case run with SQLite 3.6.16 and 3.7.0.

$ sqlite3 prova.db[[BR]]
SQLite version 3.6.16[[BR]]
Enter ".help" for instructions[[BR]]
Enter SQL statements terminated with a ";"[[BR]]
sqlite> create table foo( d date null);[[BR]]
sqlite> insert into foo(d) values( '2009-09-09' );[[BR]]
sqlite> select * from foo where (d >= 2007-01-01);[[BR]]
2009-09-09[[BR]]
sqlite> select * from foo where (d <= 2010-01-01);[[BR]]
sqlite> select * from foo where (d <= '2010-01-01');[[BR]]
