Foremost, its interesting, why your replies populate as distinct thread rather than of continuing one. (I may be incorrect, are you choosing "forward" option while replying, no ?). Request to hold the continuity of the post instead of different chunks for each reply. :)

This time I have not tweaked ActivePython binary files like I did for AP 3.2, I have just enabled Active Python 2.7 in my path while compiling source. export PATH=/opt/ActivePython-2.7/bin:$PATH ./configure --prefix=/usr/local/pg93b2 --with-python make shared_libpython=yes make shared_libpython=yes install export PYTHONHOME=/opt/ActivePython-2.7/ export PYTHONPATH=/opt/ActivePython-2.7/bin:$PATH export LD_LIBRARY_PATH=/usr/local/pg93b2/lib export LD_LIBRARY_PATH=/opt/ActivePython-2.7/lib:$LD_LIBRARY_PATH -bash-4.1$ ./psql -p 4444 psql (9.3beta2) Type "help" for help. postgres=# postgres=# create language plpython2u; CREATE LANGUAGE By chance if you have missed this part of the PG documentation reading, then please go through it, it has clear instructions of how you enable Plpython2 or Plpython3. In particular, the tip section http://www.postgresql.org/docs/9.3/static/plpython-python23.html "*Tip:* The built variant depends on which Python version was found during the installation or which version was explicitly set using the PYTHON environment variable; see Section 15.4<http://www.postgresql.org/docs/9.3/static/install-procedure.html>.
