text is not bytea.
source says:

This means that as far as the C type system is concerned, both bytea and
text are treated as "struct varlena". It doesn't mean that they are
processed by the same input/output functions, which they aren't.
NUL bytes are preserved in bytea, and used as terminators in text. I
don't find this surprising at all, do you?
I do found surprising it.
since both (text and bytea) I/O functions has CSTRING arguments and
resut type. - this only means a user should perform some unescaping on
the bytea value he got. THE SAME THING he should do with a string value
if he decide to use type text and to escape NUL-bytes before input.
then what a difference bitween those types except strlen() ?
