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.
