I forgot to mention that you can (and always have been able to) call
other functions using plpy.execute("SELECT some_func()"). If you need
to invoke Python functions, you can also just 'import' the module like
any other Python code and avoid the overheads of converting data too
and from PostgreSQL data types. You may need to ensure the PYTHONPATH
environment variable gets set correctly if you need to import your own
code from the filesystem rather than the standard library.
