I have installed newly NGL version 3.0 and at that time I have installed postgresql version 8.3.
Now I want to restore my previous backup database (NewGenLib27-10-2012.backup).
By instructed on this link (http://www.slideshare.net/Ashoksatapathy/backup-and-restore-ngl-database), I already drop schema on newgenlib and I got this error message (WARNING: errors ignored on restore: 1889).

Please guided me how to restore it.
With my best regard,
