Do you have page-level checksums enabled for these PG instances? Are you able to see if these clusters which are reporting the corruption have been restored in the past from a backup? What are you using to perform your backups and perform your restores? Are you able to see if these clusters have ever crashed and come back up after by doing WAL replay? Where I'm heading with these questions is essentially: I suspect either your backup/restore procedure is broken or you're running on a system that doesn't properly fsync data. Or possibly both. Oh, and you should probably have checksums enabled. Thanks, Stephen
