Here is an example using a plpgsql function:

create or replace function test_duplicate (p_id integer)
returns integer as $$
declarett test%rowtype;
beginselect into tt * from test where id = p_id;tt.id := nextval(pg_get_serial_sequence('test', 'id'));insert into test values (tt.*);return tt.id;
end;
$$ language plpgsql;
