You can do it either way. Hard-wiring the type OID will be a bit faster than making the server parse a ton of repetitive cast constructs, but on the other hand it means you have a magic number in your program. It's unlikely the OID assigned to bytea would ever change, but the technique doesn't scale well to user-defined types. Take your choice.
