Trigger/Query Warnings

Hi,

I've been staring at this for hours and was hoping somebody could
point me in the right direction.

I have a trigger setup on a table to update some values based on the
values being inserted/updated and keep getting warning messages in the
logs, even tho this query has the desired effect and the values are
updated in the database:

2011-09-20 15:20:50 BST WARNING: here, 'email':3B
'jake(at)stride(dot)me(dot)uk':2B 'test':1A
2011-09-20 15:20:50 BST CONTEXT: SQL statement "UPDATE resource_field_values

WHERE
boolean_value=true AND
resource_type_field_key='6830cfe2-ba89-446e-8baf-da852050bff2' AND
key!=NEW.key AND
resource_key IN
(

FROM
resource_field_values e,
resource_field_values t,
resources r

--AND
--lower(trim(e.varchar_value)) = lower(trim(NEW.varchar_value))
)"
PL/pgSQL function "process_newsletter_email_address" line 5 at SQL statement

I'm confused as line 5 is surely updating the uuid value for
updated_by. Any help/pointers would be much appreciated and I've
included the trigger that calls this is:

CREATE TRIGGER process_newsletter_email_uniqueness
BEFORE INSERT OR UPDATE ON
"e57550ed-06d9-46a8-be4f-bf8192d7ad5d".resource_field_values
FOR EACH ROW
WHEN (
NEW.resource_type_field_key='6830cfe2-ba89-446e-8baf-da852050bff2' AND
NEW.boolean_value = true
)
EXECUTE PROCEDURE
"e57550ed-06d9-46a8-be4f-bf8192d7ad5d".process_newsletter_email_address();

And the function looks like:

CREATE OR REPLACE FUNCTION
"e57550ed-06d9-46a8-be4f-bf8192d7ad5d".process_newsletter_email_address()
RETURNS trigger
LANGUAGE plpgsql
AS $$
BEGIN

THEN

resource_type_field_key='6830cfe2-ba89-446e-8baf-da852050bff2' AND
--resource_key!=NEW.resource_key AND
resource_key IN

END IF;
RETURN NEW;
