37.15. column_privileges #

视图 column_privileges 识别授予当前已启用角色或由当前已启用角色授予的列的所有权限。每种列、授权人和受权人的组合有一行。

The view column_privileges identifies all privileges granted on columns to a currently enabled role or by a currently enabled role. There is one row for each combination of column, grantor, and grantee.

如果某个权限已授予整个表，它将以每列一个授予的方式显示在该视图中，但是仅授予列粒度可能的权限类型：SELECT、INSERT、UPDATE、REFERENCES。

If a privilege has been granted on an entire table, it will show up in this view as a grant for each column, but only for the privilege types where column granularity is possible: SELECT, INSERT, UPDATE, REFERENCES.
