I get: (platform is Fedora 13, git tip, perl 5.10.1):
   andrew=# CREATE OR REPLACE FUNCTION url_decode(Vkw varchar) RETURNS   varchar  AS $$   andrew$#     use strict;
andrew$#    use URI::Escape;   andrew$#     return uri_unescape($_[0]); $$ LANGUAGE plperlu;   CREATE FUNCTION
andrew=#select url_decode('comment%20passer%20le%20r%C3%A9veillon');              url_decode
------------------------------    comment passer le réveillon   (1 row)
 
   andrew=#

which makes it look like we might have some double escaping going on 
here, but at least I don't get nothing :-)

Further experimentation shows even more weirdness. There's definitely 
something odd about the utf8 handling. Will dig further.
