Hi,
I am currently having the corrupted tables issues
described in the following link (possibly caused by
power failure,
http://archives.postgresql.org/pgsql-admin/2003-04/msg00012.php).
Since we have our systems being deployed to different
clients (psql 7.2.3), upgrading the entire database
(with data migration) will be the least preferable
solution. I am thinking of creating a script that
periodically check the relfilenode inside the pg_class
and if there is any mismatch between what pg_class
described and what actually exists in the file system,
the script will touch that file and try to drop the
table. However, once I wrote the script and started
testing it, I found that there are already some files
(mainly pg_*) tables/indexes are not being consistent
with the filesystem. Is it going to harm the database
if I blindly touch those files? Or is there any
workaround/trick/patch I can apply to version 7.2.3
without upgrading the whole database?
Thanks,
--szeming
