Thanks for the response Tom.  I understand this would be a mammoth task.

Would a more feasible approach be to introduce new types (say, TEXT2 and JSONB2 - or something better-sounding) which are the same as the old ones but add for support \u0000 and UTF 0?  This would isolate nul-containing byte arrays to the implementations of those types and keep backward compatibility by leaving TEXT and JSONB alone.

No.  It's basically never going to happen because of the widespread use
of C strings (nul-terminated strings) inside the backend.  Making \0 a
legal member of strings would break all those internal APIs, requiring
touching far more code than anyone would want to do.  It'd likely break
a great deal of client-side code as well.
