Обсуждение: pg_log: no such file or directory
Hi, I use postgresql 7.2. Last night i received a strange error and the postmaster was crashed. It reported 'cannot read block 1470 of pg_log: no such file or directory'. While googling i found, "You can change "/\name/" to "/name/" in src/backend/catalog/genbki.sh, then re-make install in that directory; or just use the latest nightly snapshot." But in script src/backend/catalog/genbki.sh, i donot find any string "/\name/". Rather i find "/ name/" at one instance. Do i have to make my change here and re-make? Or i have to upgrade to latest version? In which case i can able to recover my data? How do i recover my data then? Valuable suggestions are very welcome. TIA. regards, bhuvaneswaran

There is no pg_log in 7.2. You'll need to be more accurate about your
situation if you want help ...

Is there any other way to recover, in absence of backup? Please let us know. For your reference, here is the log: database system was interrupted being in recovery at 2002-10-28 16:34:50 IST This propably means that some data blocks are corrupted and you will have to use last backup for recovery. DEBUG: CheckPoint record at (2, 1439679740) DEBUG: Redo record at (2, 1439679740); Undo record at (0, 0); Shutdown FALSE DEBUG: NextTransactionId: 48106942; NextOid: 3022880 DEBUG: database system was not properly shut down; automatic recovery in progress...

Yow, 7.0. You should probably upgrade soon. 7.3 will be released in a few weeks. --------------------------------------------------------------------------- Bhuvan A wrote: > > > I use postgresql 7.2.
