open 命令在它所使用的表不存在，且在要打开的表的条目之前不能使用此命令。（这些最小表是 pg_class、pg_attribute、pg_proc 和 pg_type。）为了允许填充这些表本身，带 bootstrap 选项的 create 会隐式打开创建的表，以便插入数据。

The open command cannot be used until the tables it uses exist and have entries for the table that is to be opened. (These minimum tables are pg_class, pg_attribute, pg_proc, and pg_type.)

Thus, the structure of the postgres.bki file has to be:

毫无疑问还有其他未记录的排序依赖关系。
