So, I'm a big fan of this idea of having a background worker that's running and (slowly, maybe configurably) scanning through the data directory checking for corrupted pages. I'd certainly prefer it if that background worker didn't fault those pages into shared buffers though, and I don't really think it should need to even check if a given page is currently being written out or is presently in shared buffers. Basically, I'd think it would work just fine to have it essentially do what I am imagining pg_checksums to do, but as a background worker. Thanks! Stephen
