 If this variable is set to `ON`, the partial index materialization ignores the killed flag and continues materialization until completion. If queries are killed during materialization due to timeout, the work done so far is wasted, and the killed query will likely be retried later, hitting the same issue.
 
 The dafault value is `ON` which means this variable is enabled.
