I see no-one responded to this: a varlena has no fixed header size, so
you can't fit it in a structure anyway. Once you're passed a pointer
you use the LEN/PTR macros to extract what you want.

Not sure what the chars are for, but perhaps it would be easiest to
treat it as a single text object with the two leading characters
signifying something?

Have a nice day,
