Re: Vacuumdb error

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
