Let's see you do that (hint: "CREATD USER ... PASSWORD" is going to
throw a syntax error before you realize there's anything there that
might need to be protected).

And you ignored the question of insecure transmission pathways, anyway.
By the time the backend has figured out that it's got a CREATE USER
... PASSWORD command, it's already way too late if the client sent it
over a non-SSL connection.

Marko has pointed out repeatedly that a plugin can catch the worst
cases of insecure passwords even when given a pre-md5'd password.
So you can use a plugin that does it that way, or if you want you
can use a plugin that throws error on a pre-md5'd password.  I do
not see a reason for us to add a boatload of questionable logic
that favors the latter approach.
