If it's missing, it's because it's not implemented. This may be because
nobody has yet come to it, or because it has been decided that it will
not be implemented for whatever reason.
If the syntax you propose is part of the SQL standard, feel free to
propose it. If it's not, you need to present a solid case for it to be
implemented.
If you propose it and there are no objections, it doesn't mean it will
be implemented right away; it'll happen much sooner if you send a patch.
