sorry, I wasn´t clear, when I sad returning Null I tried to say that new.PK
was Null, not the function result.
Try to create exactly what I sent you and you´ll see null values on that pk.
And that occurs just because that trigger was created without EACH
ROW/STATEMENT.
So, my question is, PG should return an error and not create that trigger
because ROW/STATEMENT was not specified, correct ?
