Is “At Xinye, he set up the Eight Gates Golden Lock Formation, which was broken by Xu Shu.” true?

The official histories, such as the "Records of the Three Kingdoms, Book of Wei, Biography of Cao Ren," contain no record of the Eight Gates Golden Lock Formation or Xu Shu's breaking of it; this episode was fabricated in the "Romance of the Three Kingdoms" to highlight Xu Shu's wisdom. The original text: 「单福便上高处观望毕，谓玄德曰：“此‘八门金锁阵’也。八门者：休、生、伤、杜、景、死、惊、开。」 (Source: Chapter 036.txt)
