You're crazy. For one thing, there are sometimes reasons to *not* have such
an index, and I really don't want a message I can't turn off thinking it
knows how to design a database better than me. Second, many applications
will take warnings on update as an error condition and abort; this would be
fatal to them.

Not to water down anyone's beer, but I'm personally wondering how much good
any of these warnings will do, on CREATE TABLE or ADD CONSTRAINT or
otherwise. I already get 2-4 warnings whenever creating a new table due to
keys, etc. I don't read them anymore unless one of them is an ERROR, and I
suspect that a lot of DBAs are the same.
