Question

我在Mac OS X 10.7.2上运行PostgreSQL服务器。有时是随机查询，尤其是

CREATE OR REPLACE TEMPORARY VIEW <Name> AS SELECT * FROM <Table>;

代码PGRES_FATAL_ERROR = 7和消息

失败

ERROR:  invalid page header in block 4169 of relation "pg_type"

2-5次尝试后，查询结束，没有错误。

我认为由系统驱动器上的可用空间不足引起的问题是因为应用程序正常运行而没有数据库错误，而系统驱动器上有大量可用空间。

如何指定错误导致查询失败？

更新：添加了日志

Answer 1

听起来非常像磁盘/文件系统损坏。我建议您尽快在数据库上执行转储/重新加载循环 - 如果可能的话还要检查文件系统和磁盘硬件。

不应与可用磁盘空间相关 - 这会给您带来不同的错误。

Answer 2

更有可能某些系统表已损坏。至少pg_type。由于pg_type通常非常小（十几页/块），但您的数字（4169）非常大，可能还有其他问题潜伏在吸尘之中。

PostgreSQL的神奇之处在于系统驱动器上的可用空间很小
