Has anyone successfully built Python 2 and 3 into the same installation of Postgres 9.4.4? I tried it today on Ubuntu 10.04, Python 2.6.5, Python 3.1.2 and got and error about undefined symbol: PyString_AsString. The Python docs say that PyString_* have been renamed to PyBytes_* and I find references to both under ./src/pl/plpython. Is this a bug, something I'm doing wrong, or perhaps my system is too old? make distclean ./configure --with-openssl --with-libxml --with-libxslt --with-python PYTHON=/us r/bin/python make ./configure --with-openssl --with-libxml --with-libxslt --with-python PYTHON=/us r/bin/python3 make make install service postgresql restart psql -U postgres postgres=# create database py2; CREATE DATABASE postgres=# create database py3; CREATE DATABASE postgres=# \c py2 You are now connected to database "py2" as user "postgres". py2=# create extension plpython2u; CREATE EXTENSION py2=# \c py3 You are now connected to database "py3" as user "postgres". py3=# create extension plpython3u; ERROR: could not load library "/usr/local/pgsql/lib/plpython3.so": /usr/local/p gsql/lib/plpython3.so: undefined symbol: PyString_AsString -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
