Yeah, it would help to stop using format_operator and just print the
bare name of the operator. (format_operator can actually make things
a whole lot worse than depicted in my example, because it may insist
on schema-qualification and double-quoting.) In principle that could
be ambiguous ... but the pg_amop entry has already been identified fully,
and I don't think it needs to be part of the charter of this printout
to *also* identify the underlying operator with complete precision.
I'm still not sure how to cram the operator name into the output
without using a colon, though.
