Are you sure? The intermediate form for bytea (escaped single-quoted
strings) is pretty inefficient, but once in the database the data is
stored as binary and can even be compressed.
Plus, I'm pretty sure the protocol supports transmitting bytea fields
as binary over the wire if your client software can handle it.
