But actually that 1 free byte in the header is not currently just waste of space. If you have any nulls in your tuple, there's going to be a null bitmap in addition to the header. 1 byte is conveniently enough to store the null bitmap for a table with max 8 columns,


Are we actually doing that ? I.E are null bitmaps really allocated in 1
byte steps nowadays ?

Yes.
