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
WHEREparent = $1 AND 
 
active_flagLOOP
 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 ;
