URL Decoding

Hi List !

I am looking for an easy URL decoding function.
I thought about using regexp_replace, but I cna't get it to work :

SELECT regexp_replace('foo%B5bar', '%(..)', '\x\\1' , 'g');

'fooxB5bar'

I wanted to replace %BE with the character \xB5 (�, I think), but of
course I am doing this wrong...
Is there a simple way t odo this ?

I was simply using a stored function using pl/pythonu with
urllib (split and unquote). Works flawlessy :-)

Thanks for the tip Tino, but that means installing pythonu.
I'd like to avoid that, since I won't use it for anything
but this function.

Yes, but it would not hurt imho. Maybe you can use it for further
datamanipulation once you have it :-) plpythonu comes with postgres
so its just like configuring your database. Btw, I think pl/perl and
friends are able too, if these languages mean more for you.
