Previously `cFetcher` could decode an interleaved table's `NULL` value which would set the NULL in the corresponding column vector but would not unset the null while it should have. Release note (bug fix): Previously, CockroachDB could incorrectly consider non-NULL value from an interleaved parent table to be NULL when the interleaved child has NULL value in the row with the corresponding index key, and now this has been fixed.
