What pitfalls hides this approach? Convert python2 code to python3 it is really bad practice.
I may not understand that second sentence.  We have multiple buildfarm members
verifying the python2 case and multiple members verifying the python3 case.


I wrote about special python3 features what not testing today. We testing Python3 as subset of Python2.
The PL/Python implementation does not view them as different languages;
But it is really different languages.

If we do not want to have two different code base, then it is necessary to use than this: https://pythonhosted.org/six/

The license allows us to copy this code into postgres.
Or use standart Python tool 2to3: https://docs.python.org/2/library/2to3.html
