The Compute-related changes are OK after fixing the style issue.

[knizhnik]

This PR is not passing tests because just it is not enough to fix the problem with accessing too old version which was collected by GC. #6718 should be committed first.

Generally LGTM, thanks, but a few minor remarks.

[VladLazar]

Removing my review request, since it's unclear to me what the state of this pr is. Please re-request review if needed.

[arssher]

Generally LGTM. However the new test still fails, which is interesting. Note that it was untrivial to get to the source problem because of nesting errors masking each other: 1) first select sum(abalance) from pgbench_accounts failed with tried to request a page version that was garbage collected, which terminated the loop, 2) this killed endpoints which failed run_pgbench thread which raised PytestUnhandledThreadExceptionWarning exception, 3) finally assert_no_errors checked also failed during shutdown due to tried to request a page version that was garbage collected.

So the root cause is what this PR tried to prevent: tried to request a page version that was garbage collected. Why it fails? Well, due to missing #7377 (PR not rebased yet), as some comment above shows.
