These should not have existed to begin with, but there was apparently some misunderstanding of the purpose of the opr_sanity regression test item that checks for operator implementation functions with their own comments. The idea there is to check for unintentional violations of the rule that operator implementation functions shouldn't be documented separately .... but for these functions, that is in fact what we want, since the variadic option is useful and not accessible via the operator syntax. Get rid of the extra pg_proc entries and fix the regression test and documentation to be explicit about what we're doing here.
