I can understand why you say that for something as simple as a BYTEA, but if the value to be passed to the client is an ARRAY of geometric types or something, you gonna need an open, platform-agnostic exchange format between the way postgres internally represents it and the way the client represents it (in my case, a python list containing instances of python classes representing boxes, etc, it'll be different for every language). Exporting data from postgres in binary is only useful to C programmers who can import the required struct definitions, and you still have to manage the format, it's just that you walk struct's instead of unescaping \'s
