You'd probably be better off in pgsql-sql@postgresql.org. Also look
under the programmers documention for the interfaces (Specific interface
questions should probably go to pgsql-interfaces@postgresql.org) There
are ways to functions in Sql, PL/PgSQL, TCL etc. etc. It all depends on
what you need to do.
Here is a quick example on writing an sql procedure with parameters:
(create table and add some data)
CREATE FUNCTION get_user_age(int4) RETURNS int4
AS 'select user_age from user_tbl where user_id = $1' LANGUAGE
'sql';
select get_user_age(2);
get_user_age
