No way! Unless you propose to make the text types null-safe (which
would mean such nontrivial projects as replacing strcoll()).
The fact that the storage formats are both struct varlena does not
mean that these types are interchangeable. I fail to see where it'd
be a good idea to mark them binary-compatible, even if there weren't
serious implementation issues.
