Not sure whether its worth optimizing, but had spotted this while browsing
the code a while back. So thought would post it anyways.

The stack usage for toast_insert_or_update() may run into several KBs since
the MaxHeapAttributeNumber is set to a very large value of 1600. The usage
could anywhere between 28K to 48K depending on alignment and whether its a
32-bit or a 64-bit machine.

Is it very common to have so many attributes in a table ? If not, would it
be worth
to allocate only as much space as required ?
