postgresql 插入执行失败

@digoal Linux version 3.2.0-67-generic (buildd@brownie) (gcc version 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu5) ) #101-Ubuntu SMP Tue Jul 15 17:46:11 UTC 2014 我们有多台服务器，系统和数据库的版本都是一样的，这次移植到新服务器出现这个问题。 至于zero_damaged_pages这个参数应该没有设置

@digoal zero_damaged_pages参数是设置成的false，至于升级内核，具体是要升级到什么版本？

1. 什么操作系统内核版本?
2. 有没有打开参数zero_damaged_pages?

从现象来看，建议你确认一下zero_damaged_pages这个参数是否打开，如果打开了，请关闭它。
如果没有打开，建议你升级内核。

                 * This can happen because mdread doesn't complain about reads beyond
                 * EOF (when zero_damaged_pages is ON) and so a previous attempt to
                 * read a block beyond EOF could have left a "valid" zero-filled
                 * buffer.  Unfortunately, we have also seen this case occurring
                 * because of buggy Linux kernels that sometimes return an
                 * lseek(SEEK_END) result that doesn't account for a recent write. In
                 * that situation, the pre-existing buffer would contain valid data

                 * always have left a zero-filled buffer, complain if not PageIsNew.
