Thread: corrupt data

Hi List

Out of some reason our data of our postgresql database has been corrupted. When we try to connect to the database we
get:

psql: ERROR:  _mdfd_getrelnfd: cannot open relation pg_type_oid_index:
No such file or directory

REINDEX does not work. We get the same error. 

pgfsck gives us: wrong blockseize.

We are using postgresql 7.3.3-1 (debian).

Thanks for any hints and feedback.
