At least we are usingi it at Skype.

Three main uses are 

1) as a glue for external libraries, like GeoIP
2) for remote calls to other databases (now we have replaced that use
with pl/proxy)
3) anything that is easier to do in python than in pl/pgsql or pure sql,
like string/list processing, encoding/decoding, etc.
4) caching something in GD

we debug it by debugging outside postgresql backend if possible, and by
inserting NOTICE'es (plpy.notice('noticetext')) if running inside
backend.

various external python modules may be less robust than standard SQL
stuff. if something crashes inside plpython, it can crash/restart the
whole backend

python manual and library reference ;)
