Re: Vacuumdb error

[Carl von Clausewitz <clausewitz45@xxxxxxxxx>]

Hi,

see the two scripts attached. First one is the postgres_maintenance.sh, and the second is the postgres_backup.sh. I've attached it, and copied, because of the antivirus filters :-) 

regards,

Carl

Maintenance:

#!/bin/sh

date >> /var/log/postgresql_maintenance.log

/usr/local/bin/reindexdb --all --username=cvc >> /var/log/postgresql_maintenance.log

echo "Reindex done" >> /var/log/postgresql_maintenance.log

/usr/local/bin/vacuumdb --all --full --analyze --username=cvc >> /var/log/postgresql_maintenance.log

echo "Vacuum done" >> /var/log/postgresql_maintenance.log

Backup:

#!/bin/sh

date >> /var/log/postgresql_backup.log

/usr/local/bin/pg_dump --create --file=/usr/NAS/mentesek/postgres/$(date +%Y%m%d).backup --format=c --no-owner --username=cvc ktv_migracio_access

echo "Backup done" >> /var/log/postgresql_backup.log

Maybe you had better show us *all* of your "routine maintenance" steps,
because there are some fairly unexplainable things in that pg_index dump.
VACUUM FULL alone wouldn't have resulted in the pg_index and pg_class
indexes' entries having updated xmins:

> "(1,43)";"49791";"0";2663;1259;2;true;false;true;false;true;true;true

and I'm wondering how come three of them have indcheckxmin true too.
I think you must be whacking the system catalogs around harder than
you've admitted to.
