Dear Friends, For client requirements, I am testing postgresql 9.0.4 on windows 7 with plpython. First I installed python 2.7 and then added python installation path to windows PATH variable. Then installed postgresql from one-click installer. Server started and every thing was ok. Then I go to create plpythonu in a database. But it failed. After searching, I found that it needs python 2.6. So I again installed python 2.6 and then dropped plpython from database and created again. It was successful. Normal python functions returning text etc. are working but when conatining
import sys from uuid import getnode as get_mac mac = get_mac() return mac
