Hi Hackers,
I found index access methods use LP_DELETE for invisible tuples,
but it seems to be ok to remove LP_USED instead of adding LP_DELETE.
I tried the following simple replacements: - '|= LP_DELETE' => '&= ~LP_USED' - 'ItemIdDeleted' => '!ItemIdIsUsed'
and then, it passed all regression tests.
Why do index access methods use LP_DELETE?
Does this change make troubles?
(However, I guess there is no advantage in the change,because unused items are not recycled until next vacuum.)
