Hi Mikhail, I tested the attached follow-up patch (nocfbot_spgistvischeckwrongtid.patch). The patch applied cleanly on top of the v02 patch series. PostgreSQL built successfully, and all regression tests passed . I also verified that SP-GiST Index Only Scan continued to work correctly after applying the patch and did not observe any build or functional regressions during my testing. I was not able to verify the reported stress-test failure because no reproducer or stress-test framework was provided.
Regards, Solai
