Another option:
rewrite your function:
CREATE OR REPLACE FUNCTION "name_add" (p_name varchar, p_created_date
date) RETURNS integer AS $$ BEGIN case when $2 is null then INSERT INTO
names(name, created_date) values (p_name, default); else insert into
names values ($1, $2); end case; return 1; end; $$ language plpgsql;
