sorry, hit the wrong key >I'd say the old index tuple was killed during the first scan:
>https://www.cybertec-postgresql.com/en/killed-index-tuples/ ... from your blog: "Whenever an index scan fetches a heap tuple only to find that it is dead (that the entire “HOT chain” of tuples is dead, to be more precise), it marks the index tuple as “killed”. Then future index scans can
simply ignore it.
I understand that, but in my case the chain is not dead so this does not explain the difference. Do I miss something?
