Yeah, ideally those columns would be regprocedure. There are
bootstrapping problems involved though with populating the initial
contents of the catalogs during initdb --- the regprocedure input
function doesn't work in that environment. (It might be possible to
hack something for pg_operator, but the circularity is rather
fundamental for loading pg_type, since the input function would need to
consult pg_type to make sense of argument types.)
In the meantime I'd suggest casting the columns to regprocedure when
querying, if you want unambiguous results. That's what pg_dump does.
Or you can cast to OID if you like numbers.
