Yes. The entire datatype I/O system is based on null-terminated
strings, so there's no easy way to fix this. If it were just an
internal problem then maybe we'd bite the bullet and do it, but
breaking every user-defined datatype in existence seems too high
a price to pay for this problem.

See bytea, though its presentation format leaves something to be desired
IMHO.

One would not. A TOASTed bytea is the appropriate column type.
