Hello! > I wonder if we should add P_ISHALFDEAD(opaque) for child page?
I am not a btree expert, but things I was able to find so far: In commit d114cc538715e14d29d6de8b6ea1a1d5d3e0edb4 next check is added: > bt_child_highkey_check(state, downlinkoffnum, > child, topaque->btpo_level); At the same time there is a comment below: > * We go ahead with our checks if the child page is half-dead. It's safe > * to do so because we do not test the child's high key, so it does not > * matter that the original high key will have been replaced by a dummy > * truncated high key within _bt_mark_page_halfdead().

BWT, have you tried to create an injection_point-based reproducer? Best regards, Mikhail.
