Hmm. By feature I assume you mean "ORDER BY ... USING" (which no-one
could find an example of) and not "requiring the operator to be part of
The only people affected would be people who defined a less-than
operator but no operator class, which you said yourself would probably
just be encouraging programmer lazyness. I wasn't suggesting removing
the ORDER BY ... USING syntax, just these two options from the sorting
In fact, I don't think we ever need to remove the syntax, just as long
as the operator is part of an operator class, it'll be fine.
