On further thought, I think I'll have to not allow '\0' and require '\000'
instead. Otherwise, how should the following be interpreted:

'\0123'

Is that '\0' followed by the literals '1', '2', and '3'? Or is it '\012'
followed by the literal '3'?

So, I'll go with '\\' or '\###' where ### is any valid octal, for both
byteain and decode(bytea, 'escape').

Comments?
