I'll do that for PL/Python for now. While on the topic of needless FATAL
errors, if you try to create a Python 3 function in a session that
already loaded Python 2, you get a FATAL error with an errhint of
Start a new session to use a different Python major version.
If you raise a FATAL error, you don't really have much choice than to
start a new session, since the current one just got nuked, no? Should
this be an ERROR?
