So, in this version, there are six copies of the deprecation notice
John wrote, rather than just one. Maybe we need more than one, but I
doubt we need six. I don't think the CREATE OPERATOR documentation
needs to mention this both when first introducing the concept and then
again when defining right_type; the former seems sufficient. I don't
think xoper.sgml needs these changes either; they interrupt the flow
of the narrative and I don't think this is where anyone would look for
a deprecation notice. I would also argue for dropping the mentions in
the docs for ALTER OPERATOR FAMILY and CREATE OPERATOR CLASS, although
those seem less clear-cut. Really, CREATE OPERATOR where John had it
originally seems like the right place.

That being said, the changes to typeconv.sgml and drop_operator.sgml
seem like improvements, so I'd keep those.
