I seem to have more dead rows now..
doing a vacuum full on pg_class gives me

Total query runtime: 4469 ms.
I've restarted the server which should have got rid of any
outstanding/long running transactions - which it though was the major
cause of lingering dead rows.
Any ideas how to fix this as i'd like to reduce this from 150+Mb which
can't be good for performance....
Thanks
