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?).
pgsql-general by date:
