I'm writing a custom type in C that needs to manage two byte arrays

output functions):
typedef struct example {
bytea* first;
bytea* second;
} example;
You can't do that; the value of a datatype has to be a single chunk of
memory, and it has to be independent of exactly where it's stored
because it will get copied around without modification.

Ok, that makes sense, thanks. Guess I'll stick to a bytea and an extra
index.
Cheers,
Will.
