Try doing a REINDEX and see if you can recover all data blocks as it appears to me you have some data blocks messed up. If possible try taking the backup for your database as well.
We are stressing testing our application. It adds and deletes a lot of rows. Within 24 hours we ran into some sort of database corruption problem. We got this error when trying to insert into the users table.
ERROR XX001: invalid page header in block 2552 of relation "users_name_lower_idx"
The schema looks like this
create table users ( userid integer not null, name text unique not null, ... PRIMARY KEY (userid) );
create index users_name_lower_idx on users (lower(name));
Then the box froze up. We suspect it might ran out of IO bufs.
We are using Postgre 7.4.2 running on FreeBSD 6.1 and Dell 2850.
Thanks for any help,
