What do you mean "try"? It seems a little dangerous to just try to
compile until it doesn't throw an error. 

Consider the following program:
 len('aaaaaaaaaaaaaa')

Is that ruby or python? It's probably python, because python has a
built-in function "len". However, ruby doesn't know that the "len"
function doesn't exist until runtime -- so perhaps it's just a ruby
program that happens to throw a runtime error?

I would actually lean the other way and say that we shouldn't be
introducing behavior-changing GUCs (except for the special case of
supporting legacy behavior, like standard_conforming_strings). If we
have a default (for DO and CREATE FUNCTION), why not hard-wire the
default to plpgsql?
