I have quite the same problem. When I lauch a vacuumdb, I have an error : ERREUR: en-tête de page invalide dans le bloc 39639 de la relation base/16384/599662 With a SELECT * FROM pg_catalog.pg_largeobject Result is ERREUR: en-tête de page invalide dans le bloc 39639 de la relation base/16384/599662 I suppose that the data of LargeObject 599662 are corrupted... Question is : How I could I know where this LargeObject is used ? I can, of course, use the "zero_damaged_pages = on" option in postgresql.conf. Then dump/restore. But in this case I didn't know where this corrupted LargeObject is used... If you have an idea... Thank you in advance. -- View this message in context: http://postgresql.1045698.n5.nabble.com/Invalid-Page-Header-Error-tp1925403p5774671.html Sent from the PostgreSQL - general mailing list archive at Nabble.com. -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
