Hello, I am in the process of planning a 9.3 migration of postgres and I am curious about the checksum features available. In my test 9.3 instance it seemed like this feature provides a log entry of the exact database/oid of the corrupt object when it is accessed, but not much else. I can't find much documentation on anything else this feature provides. Is there a built-in method of scanning the server to check for corruption or will I have to wait for a corrupt object to be accessed to see the log entry? Is there a relation that stores last checksum status or anyway of reporting on what objects are identified by postgres as corrupt or not corrupt? Are there any other features of the checksum I am missing besides the log entry?
I could not find anything and the reasons for that would seem to a result of this sentence:
"The checksum is not valid at all times on a data page!!" from the below where the gory details are laid out: src/backend/storage/page/README
Thanks Mike
