No.  But you can fake many versions of this with a family of functions:

CREATE OR REPLACE FUNCTION foo(i IN int, j IN int) ...

CREATE OR REPLACE FUNCTION foo(i IN int) ... return foo(i, 1) ...

Remember that PG lets you "overload" a function name by using the same
name with different parameter lists.
