Here's a proposed addition to opr_sanity.sql for that:
-- Show all the operator-implementation functions that have their own
-- comments. This should happen only for cases where the function and
-- operator syntaxes are equally preferred (and are both documented).
-- Because it's a pretty short list, it's okay to have all the occurrences
-- appearing in the expected output.
WITH funcdescs AS (
SELECT p.oid as p_oid, proname, o.oid as o_oid,
obj_description(p.oid, 'pg_proc') as prodesc,
'implementation of ' || oprname || ' operator' as expecteddesc,
obj_description(o.oid, 'pg_operator') as oprdesc
FROM pg_proc p JOIN pg_operator o ON oprcode = p.oid
WHERE o.oid <= 9999
)
SELECT p_oid, proname, prodesc FROM funcdescs
WHERE prodesc IS DISTINCT FROM expecteddesc
AND oprdesc NOT LIKE 'deprecated%'
ORDER BY 1;
In HEAD, this query produces
p_oid | proname | prodesc

The first five of these, I believe, are the cases I left alone back in
commit 94133a935414407920a47d06a6e22734c974c3b8. I'm thinking the
other six are the ones Andrew needs to remove the DESCR entries for.
