Hi,
So I've been trying to get a plpython function that removes accented
letters, based on a Python snippet posted on another thread. The
function is simple enough:
create or replace function unaccent(text) returns text language plpythonu as $$
import unicodedata
s = unicodedata.normalize("NFKD", args[0])
s = ''.join(c for c in s if ord(c) < 127)
return s
$$ ;
However, on HEAD this is crashing for me, and it's right when plpython
loads. Backtrace below.
I already distclean'ed, initdb'd, rebuilt the whole thing from scratch
and I can't make it work. This is on Python 2.5.4, Debian unstable
stuff.
On 8.3 it just fails thusly:
alvherre=# select unaccent('álvaro muñoz');
ERROR: plpython: function "unaccent" failed
DETALLE: <type 'exceptions.TypeError'>: normalize() argument 2 must be
unicode, not str
Obviously I don't know Python to fix it :-)
