Hello,
 
I have the following error and I'm a bit worried:
 
SELECT COUNT(*) AS total FROM (SELECT "oid", * FROM "public"."lock") AS sub
-> ERROR:  invalid page header in block 0 of relation "lock"
delete from lock where bildschirmnr=16
-> ERROR:  invalid page header in block 0 of relation "lock"
Any ideas whats going on?
Thanks for any help
Michaela
