We at Skype or more precisely Sven Suursoho :) , has added these to the version of plpython in the core and they will be available in 8.2. Code for 8.0 and 8.1 will be available on request, and soon also from https://developer.skype.com/ Enchancements added are: * named parameters (args[] still valid) * returning composite types (dict, tuple, list, class) * returning SETOF as any iterable object (list, tuple, iterator, generator) -- Hannu Krosing Database Architect Skype Technologies OÜ Akadeemia tee 21 F, Tallinn, 12618, Estonia Skype me: callto:hkrosing Get Skype for free: http://www.skype.com ---(end of broadcast)--- TIP 6: explain analyze is your friend

SRF - even lazy ones (e.g. generators) work nicely there. Regards Tino Wildenhain ---(end of broadcast)--- TIP 2: Don't 'kill -9' the postmaster
