Problems with disabling triggers in Postgres 7.3.9

Hi all,

I have a problem in a trigger that disable all the triggers of a table. This
error occurs randomly and my guess is that occurs when i have a lot of
concurrents inserts in the table participation.

The error is :  RelationBuildTriggers: 2 record(s) not found for rel
participation

I search all the web and not found a solution...

Please help me...

This is my trigger code :

CREATE OR REPLACE FUNCTION buy4tickets() RETURNS "trigger" AS
