Hey Dear List,
could somebody point me to some ressources about getting only parts of toasted data?

I have a very big custom type and I would like to take blocks of it (like byte A to B then byte C to D then... ).

I found a function in http://doxygen.postgresql.org/tuptoaster_8c.html# called toast_fetch_datum_slice, is it the right way to use it

(a for loop and calling it several time?).

Thanks,

Cheers

Rémi-C
