On most (possibly all) platforms, it is not possible to use
PL/Python based on Python 2 and PL/Python based on Python 3 in the
same session, because the symbols in the dynamic modules will
clash, which will result in crashes of the PostgreSQL server
process. It is possible, however, to use both PL/Python variants
in the same database, from separate sessions.
