That is probably because you did not passed a parameter when defined the trigger. You can follow the model at [1]. When creating the trigger, you have to use a string parameter with the name of the field with the date value used for the partition.

Hi Matheus, Yes. You are right. Now it's OK. I thought that the trigger function cannont vehicle any arguments. I had mis-interpreted this phrase of the Documentation :
function_name
A user-supplied function that is declared as taking no arguments and returning type trigger, which is executed when the trigger fires.
