I bet it's the difference between prepared/not prepared plans. The
trigger prepares the plan without considering the actual parameter
values, on the psql prompt you give the parameter values explicitly in
the sql. Try to use the PREPARE command to prepare the plan on the psql
prompt, and EXPLAIN EXECUTE it to see how it works in the trigger...

Cheers,
Csaba.
