Hello
you can't to use parameters inside literal. There hasn't any sense (to
8.3, 8.4 will support USING).
you have to use serialisation to string and quoting.
some like
CREATE OR REPLACE FUNCTION foo(int[])
RETURNS SETOF int AS $$
DECLARE r record;
BEGIN
FOR r IN EXECUTE

I was wondering why USING clause is not supported in pl/pgsql dynamic
statement. Serialization is the option I tried to avoid, but it seems there
is no better approach available.
Just to say a few more about the usage
[][].

Hi,
I am trying to implement a PL/PgSQL function as following:
CREATE OR REPLACE FUNCTION sort_by_d_idx (nids INT[][], tbl_name VARCHAR)
RETURNS varchar[]
AS $$
DECLARE
result varchar[];
BEGIN
EXECUTE 'SELECT ARRAY(SELECT t.idx FROM generate_series(array_lower($1,1),
array_upper($1,1)) AS
