I was trying to find some way to implement multithreading into my postgreSQL

PG 8.3 has strict rule what CTYPE and LOCALLE is allowed. It is protection
before possible problems with data processing. You probably need set en_AU.uft8

Sorry for the quoting. I guess this probably won't be OK too :-)
Strange thing about this is that there is no simple way to use
more CPUs for one function. It can be done with external functions
but why
Short answer is: use en_AU.UTF-8 for your locale. If it doesn't exist
you can create it using /etc/locale.gen (assuming you're running some
kind of linux)
I've just installed that locale on my system (Debian Sarge). However I'm
still getting the error. I only set the locale for that user,

So the indexes were indeed bloated. There are some known usage patterns

I'm still investigating on how to return array elements.
I came out with something like:
create or replace function auz(out _errcode int, out _errmsg text)
returns setof record as $$
declare
errcode int[];
errmsg text[];
_row record;
begin
errcode[1]:=1;

You can avoid the temp table and return `setof record'. Just `RETURN
NEXT temp_result' after each test, where temp_result is your declared
working variable. When you're done with all tests, do the final RETURN.
