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.
