Обсуждение: defaults in a function

Hi,
In python when I create a method/function is set a default value for a 
passed value if one is not provided.

def foo(self, event = None):

In the above function if the second value is not passed a value of None 
is used as the default.

Is this possible with plpgsql???

http://www.postgresql.org/docs/9.0/interactive/sql-createfunction.html

... param_n type DEFAULT value
OR
... param_n type = value

It is SQL DDL syntax and not specific to the language the function is written in.
