Hi,

Can a posting item / ItemPointer belonging to posting list/tree of
some entry "stored" in a GIN index be "lossy"? If yes, under what
circumstances would such a lossy ItemPointer be included for the
entry?

I got an impression that there may be some lossy ItemPointers stored
in a GIN index while reading keyGetItem() code in
src/backend/access/gin/ginget.c
