Hello, I have this doubt since I started using PostgreSQL, a few months ago.
Why triggers are defined that way? I mean, in others DBMS you simply write:
CREATE TRIGGER <trigger_name> ... bla bla bla
BEGIN
....
END;
Why you should write a function first and then the trigger, which must call that function?
What are the advantages/disadvantages of that? Where can I find more information?
