Hmm. Maybe you should try taking this to the pgadmin-support list.
Your script came out sort of mangled in email, and apparently has
funny characters in it because I couldn't copy/paste and modify -- I
had to retype. But this runs fine in psql for me: (Printing the
hundreds of x's omitted from the post, but that looks OK to me,
too.)
test=# create table txt (val text);
CREATE TABLE
test=# insert into txt values (repeat('x', 4500));
INSERT 0 1
test=# insert into txt values (repeat('x', 4685));
INSERT 0 1
test=# select char_length(val), val is null, (val ~ 'x') from txt;
char_length | ?column? | ?column?
-------------+----------+----------
4500 | f | t
4685 | f | t
