关于QUERY_REWRITE_INTEGRITY的疑问
?QUERY_REWRITE_INTEGRITY: This parameter can also be reset dynamically for the instance and for an individual session. It accepts the following values:
-Enforced (the default): Enables query rewrites only if the server can guarantee consistency. Only up-to-date materialized views and enabled validated constraints are used for query rewrites.
-Trusted: Allows query rewrites based on declared, but not necessarily enforced, relationships. All updated materialized views and constraints with the Rely flag are used for query rewrites.
-Stale_tolerated: Allows query rewrites to use materialized views that have not been refreshed since the last declared DML operation and relationships.
Enforced：只有在server可以保证一致性的时候，才允许query rewrite使用MV。
Stale_tolerated：从字面上就可以看出，即使是陈旧的MV，也允许query rewrite使用。
但这个Trusted大概是个什么意思呢，实在是翻译不好，请各位帮助，谢谢
