Обсуждение: Problem with pg_log file corrupted

Hi,
I think the pg_log file of my postgreSQL is corrupted after a power
failure.
I can;t access to tables in my database now.
The error message appear when I tried to list all tables is as below :
" cannot flush block 8 of pg_log to stable store "
Anybody know how can I restore back the pg_log file.
Thanks.

I can't see any good reason why you'd get a failure there ... unless
maybe you are out of disk space?

Assuming you are running a 7.0.* release, I'd suggest updating to 7.0.3,
which will at least give a more detailed error message.

I am using postgreSQL version 6.5.3
I think probably the transaction was inconsistent when there is a power
failure
when user try to update data to tables through webpage.
Now, I can't do #pgaccess [database name] ....
It will prompt me the same error saying cannot flush block 8 of pg_log
file.....
Since pg_log file is a binary file, I don;t know how to restore it...
I tried to delete the file but then, I can;t open any database without the
file.
I am trying to upgrade the postgreSQL version now...see whether it helps.
Thanks.
