Previously, even when `EXPLAIN` output tells that we will do index-only scan, it was never the case since columnar tables don't have the visibility fork that postgres is looking for. For this reason, visibility check done in `IndexOnlyNext->VM_ALL_VISIBLE` code-path was always returning false and postgres was reading the tuple from the columnar relation itself. |
