Keith: This is the general approach I use over and over and over -- This is 
a PLPGSQL function that returns a SETOF

tablename%ROWTYPE

If you need the full schema and table and everything that goes with this --  
let me know --- 

CREATE OR REPLACE FUNCTION sys_aclsubmenu(int4) RETURNS SETOF 
sys_tree_components AS
$BODY$

DECLARE MNU ALIAS FOR $1;
DECLARE OUT sys_tree_components%ROWTYPE;
DECLARE CHILD sys_tree_components%ROWTYPE;
BEGIN

 RAISE NOTICE 'sys_aclsubmenu(integer, varchar) called for item: %', $1;
 FOR OUT IN SELECT * FROM sys_tree_components WHERE parent = $1 AND 
active_flag
 LOOP

  IF (OUT.id != OUT.parent) THEN

   FOR CHILD IN SELECT * FROM sys_aclsubmenu(OUT.id) LOOP

    RETURN NEXT CHILD;

   END LOOP;

  END IF;
  RETURN NEXT OUT;

 END LOOP;
 RETURN;

END;

$BODY$ LANGUAGE 'plpgsql' VOLATILE;

SELECT * FROM sys_aclsubmenu(1) ORDER BY parent, id ;
