What is this needed for? C code can internally do whatever it wants,
and the database encoding is effectively a constant, so there is no need
for server-side code to be very much concerned about whether types do this.
Also, "types" is perhaps the wrong subject here. Types only contain
input and output functions and a few more bits. Additional functions
operating on the type could look at the server encoding without the type
and its core functions knowing about it.
