Well, you'll get me first in line to back that the current default is stupid.
But I'm not sure sslmode=require is a proper default either. Because
then the connection will fail completely to the vast majority of
servers, which simply don't have SSL support.

Yeah, a prefix based solution would fix this, since we can keep throwing errors.
However, not throwing errors on the URL syntax should be considered a
bug, I think.
