However if you want to make an attempt to recover you can do: 1) make a physical backup of this cluster 2) in your postgresql.conf set 'zero_damaged_pages = on' [1] 3) start your cluster I really don't know if it will work, but you can try... :-) Regards, [1] http://www.postgresql.org/docs/9.2/static/runtime-config-developer.html#GUC-ZERO-DAMAGED-PAGES -- Fabrízio de Royes Mello Consultoria/Coaching PostgreSQL >> Blog sobre TI: http://fabriziomello.blogspot.com >> Perfil Linkedin: http://br.linkedin.com/in/fabriziomello >> Twitter: http://twitter.com/fabriziomello
