I'm quite sure I said I'd open source my MySQL implementation, which allows
Postgres to appear to MySQL clients as a MySQL/MariaDB server. This is
neither proprietary nor Amazon-related and makes Postgres substantially
more useful for a large number of applications.

As Jan said in his last email, they're not proposing all the different
aspects needed. In fact, nothing has actually been proposed yet. This is an
entirely philosophical debate. I don't even know what's being proposed at
this point - I just know it *could* be useful. Let's just wait and see what
is actually proposed before shooting it down, yes?
