[GENERAL] pg_dump error

[Stefano Zampieri]

hi,
I've experienced an error while doing
pg_dump dbname > dump_file

"failed sanity check, type with oid 145670 was not found"

the same error for pg_dump -s
no errors with pg_dump -t tablename for each table of the db

Does anyone know what this mean and how to fix it?

-postgres 6.3.2 RH linux 4.2

Thank you in advance
