I think I know your problem.  Look at this:

    test=> create table test5 (x varchar(5));
    CREATE
    test=> insert into test5 values ('Z ');
    INSERT 18698 1
    test=> insert into test5 values ('P');
    INSERT 18699 1
    test=> insert into test5 values ('S');
    INSERT 18700 1
    test=> insert into test5 values ('Z');
    INSERT 18701 1
    test=> select * from test5 where x between 'P' and 'Z';
    x
    -
    P
    S
    Z
    (3 rows)

Notice in a varchar field, spaces are significant.  This is not true in char(5)
field, so 'Z ' is not between 'P' and 'Z'.  We can change this, but I
think this the way it is supposed to work.  Using < and > yields the
same result.
