Forgot to mention --- I'm not in favor of backpatching.  First because
tightening encoding verification has been a process over multiple
releases; it's not a bug fix in the normal sense of the word, and might
break things that people had been doing without trouble.  Second because
I think we'll have to change pg_verifymbstr's API, and that's not
something to back-patch if we can avoid it.
