I tested the v02 patch series.
The patches applied cleanly and PostgreSQL built successfully.
I created a GiST index and verified that the query uses an Index Only
Scan (Heap Fetches: 0). I also tried to reproduce the reported race
condition by running concurrent Index Only Scans together with DELETE
and VACUUM operations, but I wasn't able to reproduce the issue
manually. Since this is a timing-dependent race condition, that wasn't
too surprising.
After applying the patches, I rebuilt PostgreSQL and ran the test
suite. All 245 tests passed, including the new regression test added
by this patch, and I didn't notice any regressions during my testing.
Overall, the patch applied cleanly, built successfully, and my testing
didn't reveal any issues.
