Backport 1/1 commits from #121904 on behalf of @yuzefovich.

/cc @cockroachdb/release


This commit fixes a possible incorrect result of evaluation of the IN expression where the left side is INT2 or INT4 type and the right side has integers outside of the range of the left side's type. We do so by upcasting the "filter" row to INT8. Note that we already do the appropriate upcast in the comparison function, so the incorrect results could only be produced due to the "filter row" no longer being sorted in case a value overflows.

Fixes: #102864.

Release note (bug fix): CockroachDB could previously incorrectly evaluate IN expressions that had INT2 or INT4 type on the left side and values outside of the range of the left side on the right side. The bug has been present since at least 21.1 and is now fixed.


Release justification: bug fix.

Thanks for opening a backport.

Please check the backport criteria before merging:

  • Backports should only be created for serious
    issues
    or test-only changes.
  • Backports should not break backwards-compatibility.
  • Backports should change as little code as possible.
  • Backports should not change on-disk formats or node communication protocols.
  • Backports should not add new functionality (except as defined
    here).
  • Backports must not add, edit, or otherwise modify cluster versions; or add version gates.
  • All backports must be reviewed by the owning areas TL and one additional
    TL. For more information as to how that review should be conducted, please consult the backport
    policy
    .
If your backport adds new functionality, please ensure that the following additional criteria are satisfied:
  • There is a high priority need for the functionality that cannot wait until the next release and is difficult to address in another way.
  • The new functionality is additive-only and only runs for clusters which have specifically “opted in” to it (e.g. by a cluster setting).
  • New code is protected by a conditional check that is trivial to verify and ensures that it only runs for opt-in clusters. State changes must be further protected such that nodes running old binaries will not be negatively impacted by the new state (with a mixed version test added).
  • The PM and TL on the team that owns the changed code have signed off that the change obeys the above rules.
  • Your backport must be accompanied by a post to the appropriate Slack
    channel (#db-backports-point-releases or #db-backports-XX-X-release) for awareness and discussion.

Also, please add a brief release justification to the body of your PR to justify this
backport.
