The original representation uses "opcname for amname", which is good enough; but if we replace "for" with "using", we can apply the returned identity directly in a DROP command, as in DROP OPERATOR CLASS opcname USING amname This slightly simplifies code using object identities to programatically execute commands on these kinds of objects. Note backwards-incompatible change: The previous representation dates back to 9.3 when object identities were introduced by commit f8348ea3, but we don't want to change the behavior on released branches unnecessarily and so this is not backpatched.
