PR: cockroachdb/cockroach#67450

From release notes:

The [vectorized execution engine](../v21.2/vectorized-execution.html] can now perform a scan over an index, and then join on the primary index to retrieve the required columns. [#67450][#67450)

Jira Issue: DOC-1383

Yahor Yuzefovich Do you know if this feature was ever listed as a known limitation? I can’t find anything.

Stephanie Bodoff I think we never documented that as a limitation. To be more precise, before this PR the queries would still run through the vectorized execution engine, but they wouldn’t be as efficient as they are in 21.2 release, so probably the better category for this release note would be “performance improvement”.
