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.
