Dear Hackers
In fix part oh HeapTuple, there is a union that is named t_choice,
union
{
HeapTupleFields t_heap;
DatumTupleFields t_datum;
}t_choice;
I can't find out why we need t_datum, actually there is no comment about
DatumTupleFields.
Regards
Soroosh
Hello,
I think the comment just above the HeapTupleFields struct definition
has the related details.
/*
* Heap tuple header. To avoid wasting space, the fields should be
* laid out in such a way as to avoid structure padding.
*
* Datums of composite types (row types) share the same general
Thanks,
If a tuple constructed in memory we don't need t_heap. I have another
question,
How make an in-memory tuple?

Hello,
I think a more appropriate question to be asked here would be at what
point (in the life of a typical tuple), does a tuple's header contain
t_datum or otherwise, which I would also like to be answered.

Hello,
Would you guys please trim the quoted text of the emails you're replying
to? I understand Gmail is obnoxious w.r.t. quoted text, but this is
starting to become excessive.
