Hello, I am in trouble now. Alfresco tomcat Server is starting correctly but when i try to start Postgress it starts in 2 seconds then stop. I did some investigations in postgress log files then find that every time I try to start Postgress service i got this error message "FATAL: failed to re-find parent key in index "16617" for split pages 3890/3891". I did some googling but failed to get the workaround on this problem. Can you please help me figuring out what this error means?
