create operator problem

Hello!

I use an external function in postgres and here i try create operator for
like with regional character support ::

-----< Cut begin
create function mylike(text,text) returns bool
as '/home/vip/neko/tudakozo/comp.so' language 'c';
CREATE
select mylike('Jeno','Jen'),mylike('aJenO','Jen'),mylike('fJeNof','Jen'),
       mylike('JEnke','Jen');
mylike|mylike|mylike|mylike
------+------+------+------
t     |t     |t     |t
(1 row)

select 'f:', mylike('asd','fds');
?column?|mylike
--------+------
f:      |f
(1 row)

-- It works

drop operator ~~ (text,text);
DROP
create operator ~~ (leftarg=text,rightarg=text,procedure=mylike);
CREATE
select 'this will be true'::text ~~ 'true';
?column?
--------
f
(1 row)
-- it seems not ;(
-----< Cut end

function as operator too. If that was a bug, this letter is a bug report,
but if it isn't please help me!  The used postgres's vn: 6.3-2, it runs on a
