Обсуждение: trigger error

You must have dropped and recreated the function after your trigger was 
created...
You need to recreate the trigger now, so that it picks up the new 
function id.
In the future use 'CREATE OR REPLACE' to modify a function instead of 
DROP and CREATE - this will make sure the modified function keeps its id.

I hope, it helps...

The errors mean that after the trigger definition you maded a 
modification on the function rebuilding it. Try to delete the trigger and
define it again.

The fact that you are using "RETURN OPAQUE" instead of
"RETURN TRIGGER" means that you are using a Postgres 
version prior then 7.3.x.
Using the version 7.3.x ( I suggest you the 7.3.3 ) you can 
define that funcion: "CREATE OR REPLACE .... " so you are
not forced to delete it before and your problem should gone.
