What do you mean by "PostgreSQL source code"? - SQL? pl/pgsql?
Generally, you just execute the following SQL command:
create or replace function my_function(.....) returns [return type]
as
$$
[function code here]
$$
language [whatever - usually sql or plpgsql] ;
....or am I missing something in your question?
