I have a stored proc in which I want to retur the primary key of an insert statement that the stored proc just ran. How can I do that?

If the primary key is a SERIAL column then see "How do I get the
value of a SERIAL insert?" in the FAQ:

hi,

If this primary key is a guid or a number that you create as unique, create
it local to your function and then return the same after inserting within
the function.

create or replace function test_insert() returns guid as $$
DECLARE
ret guid;
BEGIN
select into ret newid();
-- ret is the primary key for the table "Table_a"
insert into table_a (ret, "Value1","Value2");
if not found then
...............
end if;
return ret;
END;
$$ language plpgsql;

your question is too abstract, i tink we will nee more information to solve
your problem
