Yeah, I don't remember any such consensus either, but it's not a dumb
name.  I have been idly wondering throughout this process whether we
should try to pick a name that conveys the fact that these constraints
are inextricably tied to the opclass/index machinery - but I'm not
sure it's possible to really give that flavor in a short phrase, or
that it's actually important to do so.  IOW... "whatever".  :-)
