Stored Procedure Error

Hello,

I'm getting an error attempting to run the code below.  The funny thing is,
this code worked a few hours ago.

The error is:
WARNING: line 53 at return next
ERROR: Set-valued function called in context that cannot accept a set

I'm not really sure what else might be needed to debug this code.  Any help
is much appreciated.


Here is the code:

create or replace function testFunction(integer) returns setof namefilings
as '
declare
 searchid ALIAS FOR $1;
 r names%rowtype;
 r2 namefilings%rowtype;
 select_text VARCHAR;
 get_nameid VARCHAR;

BEGIN
 get_nameid := ''select nameid from names join searchvalues
   on (name = LOWER(value)) where searchid = '' || searchid;

 select_text := ''select b.* from names as a join namefilings as b
   on (a.nameid = b.nameid)
   where a.nameid IN ('';

 FOR r IN EXECUTE get_nameid LOOP
  select_text := select_text || r.nameid || '','';
 end loop;
 select_text := RTRIM(select_text, '','');
 select_text := select_text || '') limit 10'';

 FOR r2 IN EXECUTE select_text LOOP
  return next r2;
 END LOOP;
 return;
END;
' language 'plpgsql';


Thanks,
Derek
