Yeah, I was going to suggest something involving
find_rendezvous_variable to let the two versions of plpython check for
each other. But doesn't the error need to be elog(FATAL)? If you just
elog(ERROR) then the conflicting version of python.so is already loaded
and able to cause problems. elog(FATAL) isn't very desirable maybe
but it beats crashing.
Minor grammatical nit: I think "session has previously used" would read
better in the errdetail.
