Cheers tom, that did it - i've removed the duplicates and seeing what else is broken.

ERROR:  could not create unique index "pg_class_oid_index"

a quick inspection of the pg_class table doesn't show any duplicates, is there anyway i can find out which row(s) are duplicated and remove them without a full db restore?

also doing something like this doesn't return anything which worked for my other tables

select oid from pg_class where oid in(select oid from pg_class group by oid having count(oid)>1 )

Try doing it with enable_indexscan = off and enable_bitmapscan = off.
The system might be relying on the old, bogus index to do the group by
oid.

regards, tom lane
