Hi, This problem is related to an sql-ledger database, but given the nature, I think it's more appropriate here. Our sql-ledger server had a filesystem corruption. We do have backups, but it's only now, after reading the PostgreSQL manual, that I knew that it would have been a good idea to run pg_dump every now and then, via cron perhaps. We only have a filesystem backup of /var/lib/postgres. I have tried restoring the directory to a new server with postgresql not running. However, upon starting the database, sql-ledger reports database not found. It is also not listed in the psql -l command.
Well, if you restored a full backup of /var/lib/postgresql (that was taken while PG wasn't updating any data) you should be OK. The fact that you're not suggests that something is being overwritten.
Restore it again, make sure logging is turned on in your postgresql.conf and see what it says about "recovering" etc.
